Dear Shareholder:

You are cordially invited to attend the Arrow Financial Corporation Annual Meeting of Shareholders on Wednesday,

April 25, 2018, at 9 a.m. at the Charles R. Wood Theater in downtown Glens Falls, New York.

The meeting will begin with a review of all voting matters and feature a short presentation on the Company. Additional details about the meeting and voting instructions can be found in the Notice of 2018 Annual Meeting of Shareholders and related Proxy Statement.

The past year included a number of important milestones and highlights for our Company. We would like to take this opportunity to note a few of these achievements, which set us apart from our peers:

• Profitability: We reported outstanding profitability for 2017, represented by our fourth consecutive year of record net income as well as 12.14% return on average equity, 1.09% return on average assets and 13.51% return on tangible equity at year-end.

• Shareholder Value: Diluted earnings per share for 2017 were a record $2.10. Excluding a one-time benefit resulting from the Tax Cuts and Jobs Act of 2017, diluted earnings per share were $2.02. Shareholders’ equity reached a record high. In addition, cash dividends paid to shareholders effectively increased 3% in 2017, as we distributed a 3% stock dividend in September.

• Loan Growth: Our loan portfolio reached $1.95 billion with double-digit growth for the fourth consecutive year, due to growth in all three of our major segments: commercial, consumer and residential real estate. In addition, we continued to have excellent asset quality, as measured by low levels of charge-offs and non-performing assets.

• Industry Recognition: In 2017 Arrow was named one of “America’s 50 Most Trustworthy Financial Companies” by Forbes for the sixth consecutive year. The Company also appeared in Bank Director Magazine’s annual “Bank Performance Scorecard” as one of the top-performing banks in the country. Finally, both of the Company's two banking subsidiaries maintained their 5-Star Superior Bank ratings by BauerFinancial, Inc.

We are proud of our performance and these accomplishments. For a better understanding of our Company, including its compensation practices and corporate governance structure, please review our proxy materials, most recent Annual Report on Form 10-K and our other securities filings. We hope you will vote, whether or not you plan to attend the Annual Meeting. It is important to us that your shares are represented.

Voting Item 1 – Election of Directors

Summary and Board Recommendation:

The Board of Directors is divided into three classes (A, B and C), with one class to be elected at each Annual Meeting of Shareholders for a term of three years. Longtime Class B Director David L. Moynehan has decided to retire at the Annual Meeting, which is at the end of his current term. The Director classes will be re-balanced by moving one Director, Thomas J. Murphy, from Class A to Class B. Immediately prior to the Annual Meeting, the number of Directors will be reset from 13 Directors to 12: four Class A Directors, four Class B Directors, and four Class C Directors.

Item 1 at the Annual Meeting is the election of fourClass B Directors (including Mr. Murphy who was appointed a Class A Director at the 2017 Annual Meeting of Shareholders) to three-year terms expiring at the 2021 Annual Meeting of Shareholders and/or until their successors are elected and qualified. The Board has nominated for election Michael B. Clarke, David G. Kruczlnicki, Thomas J. Murphy and Raymond F. O’Conor.

1

All four nominees were unanimously recommended by the Governance Committee to the Board, have been determined to be qualified, and have consented to serve if elected.

There are no arrangements or understandings between any Director or Director nominee and any other persons pursuant to which he or she was selected as a Director or nominee. None of the Directors are party to any agreement or arrangement that would require disclosure pursuant to Listing Rule 5250(b)(3) for NASDAQ^®, where the Company’s common stock is listed.

The Board has no reason to believe that any of these nominees will decline or be unable to serve if elected. Under applicable law and the Company’s Bylaws, Directors are elected by a plurality of the shares voted at the Annual Meeting, meaning the nominees receiving the most “For” votes will be elected. For additional information regarding the vote requirements for Item 1 and a description of the Company’s Majority Voting Policy with respect to the election of Directors, please see the Additional Voting Information section.

• Vote Recommendation: Your Board recommends you vote “For” each of its four nominees:

Michael B. Clarke, David G. Kruczlnicki, Thomas J. Murphy, and Raymond F. O’Conor.

Director Nomination Process:

The Governance Committee is responsible for identifying and recommending to the full Board suitable nominees to serve as Directors, including incumbents. Director nominees are selected based upon the following criteria:

• Individual Strengths: The candidate’s knowledge, skill, experience and expertise

• Board Composition: The objective of achieving certain characteristics for the Board as a group, such as diversity of background, occupation, viewpoint and gender

• Succession Planning: Balance among age groups from those who are in mid-career to those nearing or recently entered into retirement

Additionally, the Governance Committee will not generally recommend a new candidate for nomination unless the candidate has demonstrated notable leadership and accomplishment in business, higher education, politics and/or cultural endeavors. The Governance Committee further assesses a candidate’s understanding of the regulatory and policy environment in which the Company does business and his or her interest in the communities served by the Company. Other factors considered by the Governance Committee include a candidate’s personal character, integrity and financial acumen. For candidates with prior experience as a Director of the Company or one of its subsidiaries, his or her service record will be an important factor in evaluating the desirability of his or her continuing service as a Director. Generally, Directors may not serve on the boards of more than two other public companies and may not serve on the board of any other public company whose principal business is financial services.

To identify new candidates for Director, the Governance Committee will employ its own search protocols, seek suggestions from Management and consider any Director nominee proposals it properly receives from shareholders. The same screening process is applied to all suggested candidates, regardless of the source. The Board will give substantial weight to the recommendations of the Governance Committee in selecting Director nominees for election and in filling Director vacancies. Under normal circumstances, the Board will not select nominees, including incumbent Directors, who have not been recommended by a majority of the members of the Governance Committee. For information on how shareholders may participate in the Director nomination process, see “Shareholder Submissions of Director Nominees for the 2019 Annual Meeting” in the Additional Shareholder Information section.

Director Compensation:

The Compensation Committee makes recommendations to the full Board regarding Director compensation. The Board itself, however, is responsible for determining the compensation payable to Directors for their services. Amounts paid for service on subsidiary bank boards are considered by the Board in its periodic review of total Director compensation.

4

tCompensation Components

There are three basic components of the compensation paid to Company Directors: basic annual retainer, meeting fees and incentive stock-based compensation. Only non-Management Directors receive compensation for their services as Directors. Management Directors (those persons who are also officers) receive no additional compensation for their services as Directors. Thus, Mr. Murphy, who is both a Director and an Executive Officer of

the Company, received no Director compensation in 2017, although he was entitled to reimbursement of any expenses he incurred in connection with his service as a Director.

• Basic Annual Retainer and Meeting Fees

Each non-Management Director of the Company receives a fixed basic annual retainer fee for serving as a Company Director as well as a fixed basic annual retainer fee for serving as a Director of one of the Company's subsidiary banks. Non-Management Directors also receive fees for attending meetings of the Company’s Board (and its committees) and meetings of a subsidiary bank’s board (and its committees). Moreover, if a non-Management Director serves as a Chair of the Company's Board (or one of its committees) or as Chair of one of the subsidiary banks' boards (or one of its committees), he or she will also receive a supplemental annual retainer fee commensurate with the increased responsibility accompanying such position. Directors who serve on a Company or subsidiary bank committee but do not serve as the Chair thereof do not receive a supplemental annual retainer fee.

A Director’s total annual retainer fee, including any supplemental annual retainer fee for service as a Board or committee chair, is currently paid semi-annually (May and November) in advance of the period to which such payment relates. Directors who are appointed or elected to the Board in the middle of one of these six-month periods receive a pro rata share of the annual retainer fee receivable by those Directors who serve for the entire period. This fee is paid to new Directors at or about the time their service commences.

Under the Arrow Financial Corporation2013 Directors’ Stock Plan (“2013 Directors’ Stock Plan”), the Board may electfrom time to timeto pay some or all of the Directors’ fees, including annual retainer and meeting fees, in the form of shares of Company common stock as opposed to cash. Distributions of shares in lieu of cash are made twice annually. The number of shares actually distributable to Directors is calculated based on the market price of the Company’s common stock on the date of distribution. All shares distributed under the 2013Directors’ Stock Plan in lieu of cash are fully vested and transferable by the recipient Directors on the date of distribution, subject to applicable securities laws and our stock ownership and other guidelines. In 2017, as in prior years, the Board decided to pay a portion of the basic annual retainer fee payable to each non-Management Director for such year in the form of shares of stock under the 2013 Directors’ Stock Plan.

The following table sets forth the dollar value of Directors’ fees paid in cash and/or shares of the Company’s common stock to non-Management Directors in 2017 for their service on the Company’s Board, any subsidiary bank board, and committees thereof. The table shows the basic annual retainer fees, any supplemental annual retainer fees for serving as a Board or committee Chair, and fees for Board and committee meetings attended. All changes were approved by the Board at its meeting in January 2017.

BASIC ANNUAL RETAINER FEES
2017	Company	GFNB	SNB
Basic Annual Retainer (a)	$20,000	$13,000	$11,000
Chair of Board	$9,000	$9,000	$9,000
Chair of Audit Committee	$7,500	N/A	N/A
Chair of Compensation Committee	$5,000	N/A	N/A
Chair of Governance Committee	$5,000	N/A	N/A
Chair of Wealth Management Committee	N/A	$5,000	N/A
MEETING FEES
Board of Directors (b)	$700	$500	$500
Committee of the Board (b)	$550	$400	$400

(a) In 2017, $10,000 of the basic annual retainer fee for service as a Director of the Company and $5,500 of the basic annual retainer fee for service as a Director of GFNB or SNB were paid in shares of the Company’s common stock.

(b) Per meeting attended.

5

With respect to 2018 Director compensation, at its January 2018 meeting, the Board increased the basic annual retainer by $1,000 to a total of $21,000 for the Company and by $500 for each of the subsidiary banks to a total of $13,500 and $11,500, respectively, for GFNB and SNB. All other Director fees remain the same for the Board and the Company’s subsidiary banks.

Under the Company’s Directors’ Deferred Compensation Plan, Directors of the Company and its subsidiary banks may elect to defer receipt of some or all of the cash fees otherwise payable to them in any year to a later date, subject to certain limits set forth in such plan and applicable law. Under this unfunded plan, amounts deferred are credited to the plan account of the deferring Director. The deferred amounts earn interest from time to time at a rate equal to the highest rate being paid on individual retirement accounts by GFNB. Deferred amounts are ultimately distributable on a date or dates selected by the Director, subject to certain restrictions. Distributions under the plan are payable in cash, either in a lump-sum or in annual installments as the participant may choose. During 2017, one Director elected to defer fees under the plan. See the “2017 Director Compensation Table” later in this section for additional details.

• Incentive Stock-Based Compensation

Under the Company’s current long-term incentive plan, the Arrow Financial Corporation 2013 Long Term Incentive Plan (“2013 LTIP”), the Board is authorized, in its discretion and after consultation with the Compensation Committee, to make grants of stock-based incentive awards to non-Management Directors of the Company as additional compensation for their service as Directors. The terms and conditions of awards granted to Directors are established by the Board itself, not by the Compensation Committee. The Board believes the grant of such awards, particularly in the form of stock options for the Company’s common stock, serves an important purpose by further aligning Directors’ interests with those of shareholders, as stock options only provide value to the holder if the Company’s stock price increases.

Historically, the Board has approved annual grants of a fixed number of stock options to non-Management Directors under the 2013 LTIP (and predecessor plans). Such options typically vest ratably over a four-year period, subject to accelerated vesting in the event of a change-in-control of the Company. All Directors’ stock options granted under the 2013 LTIP have a maximum term of 10 years from the date of the grant and are exercisable only while the Director continues to serve in such capacity and, in the usual case, for a short period following termination of service. The Board may elect to accelerate the vesting of options on a case-by-case basis, to extend the period of post-termination exercisability up to the maximum term of the option and has on occasion elected to do so in practice.All options granted to Directors in 2017 will vest ratably over a four-year period, reinforcing the long-term nature of the grant. The exercise price for all stock options granted to Directors in 2017 was the fair market value of the Company’s common stock on the date of grant, i.e., the reported closing price of the stock on such date.

In early 2017, the Board granted to each then current non-Management Director who also was a Director in 2016, a standard annual incentive award for a fixed maximum number of stock options under the 2013 LTIP, subject to downward adjustment in any particular case if the individual Director’s attendance record for meetings of the Company Board and committees during the prior year was less than 100%. Specifically, each eligible non-Management Director received a number of options equal to 1,000, multiplied by the Director’s “meeting attendance ratio” for the prior year, which consists of: (i) the number of meetings of the Company’s Board and its committees on which the Director serves held during the prior year that the Director actually attended, divided by (ii) the total number of such meetings held during the prior year. The number and grant date value of all such options are listed in the “2017 Director Compensation Table” later in this section.

In early 2018, the Board granted to each eligible non-Management Director for their 2017 service and under the 2013 LTIP a standard annual incentive award of stock options, generally subject to the usual terms and same maximum amount and downward adjustments, if any, as pertained to the 2017 grants described above.

tStock Ownership Guidelines

In order to better align the interests of Directors with the interests of shareholders, the Company has established individual stock ownership guidelines for non-Management Directors. Under these guidelines, each non-Management Director of the Company is expected to achieve, within five years following his or her election or appointment to the Board, and thereafter to maintain as long as he or she serves as a Director, beneficial ownership of a number of shares of the Company’s stock having a market value at least equal to five times the basic annual retainer fee payable from time to time to such Director for serving on the Company’s Board. Under normal

6

circumstances, if and for so long as a non-Management Director does not meet this target level of beneficial ownership, restrictions may be placed on the Director’s ability to sell shares of the Company’s common stock obtained through the exercise of stock option awards previously or subsequently granted to the Director under the 2013 LTIP, predecessor plans or successor plans. The target ownership requirement for each non-Management

Director is measured by the Compensation Committee as of each year-end, using holdings valued as of December 31 of such year. Common shares owned outright (including shares held jointly with a spouse) or held through

Company plans (e.g., the Company’s Automatic Dividend Reinvestment Plan) are currently counted toward the stock ownership requirement. Unexercised stock options do not count toward the stock ownership requirement. The independent members of the Board have the discretion to address and approve exceptions.

The Compensation Committee has determined that, at December 31, 2017, all non-Management Directors who have served on the Company's Board for at least five years have met the stock ownership guidelines. Management Directors are subject to a separate policy; for a description, see “Stock Ownership Guidelines” in the Compensation Discussion and Analysis section.

t2017 Director Compensation Table

The following Director Compensation Table summarizes all compensation paid by the Company and its subsidiaries to the non-Management Directors of the Company for the fiscal year ended December 31, 2017. Management Directors (who, in 2017, consisted solely of Mr. Murphy) do not receive any compensation for service as Directors of the Company or either of its subsidiary banks. Compensation received in 2017 by Mr. Murphy is reported in the “Summary Compensation Table” within the Executive Compensation section.

(g) Represents consulting fees earned and paid to Mr. Hoy under his consulting agreement. See “Mr. Hoy’s Consulting Agreement.”

(h) Represents interest earned by the listed Director during 2017 on the principal balance of the Director’s account under the Directors’ Deferred Compensation Plan.

tMr. Hoy's Consulting Agreement

Mr. Hoy, a Director of the Company and Chairman of the Board, served for many years as the Company's President and CEO prior to his retirement at the end of 2012. At that time, the Company entered into a three-year consulting agreement with Mr. Hoy, which was renewed for another three-year term on January 1, 2016. Under the agreement, Mr. Hoy renders advice and assistance regarding management and operation of the Company, as requested by the CEO or Board. In return, he receives $36,000 annually, payable in equal monthly installments. He also receives office space, administrative support and equipment as agreed by the parties for the provision of the consulting services. The agreement is generally terminable upon 30 days’ prior written notice by either party to the other and contains confidentiality and non-competition provisions in favor of the Company. Mr. Hoy has not received any additional stock options from the Company in connection with his post-retirement service to the Company as a consultant. However, all outstanding stock options granted to Mr. Hoy under the Company’s long-term incentive plans before his retirement as CEO continued to vest, to the extent unvested at his retirement, during his post-retirement consultancy. These vested options continue to be exercisable during this consultancy, and for a short term thereafter, in accordance with the terms and conditions thereof, up to the maximum 10-year term of such options. The stock options granted to Mr. Hoy under the long-term incentive plan as a non-Management Director (following his retirement as CEO) are not subject to or affected by his continuing service as a consultant to the Company.

Voting Item 2 – Ratification of Independent Registered Public Accounting Firm

Summary and Board Recommendation:

The Audit Committee of the Board has selected the independent registered public accounting firm, KPMG LLP ("KPMG"), as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018. The selection process included a thorough review of KPMG’s performance in prior years, the quality and expertise of the KPMG management team, its understanding and expertise in the industries in which the Company operates, the appropriateness of the fees charged, and its familiarity with the Company’s internal controls and accounting policies and practices.

Although Company Bylaws do not require the selection of the independent registered public accounting firm be submitted to shareholders for approval, the Board believes it is appropriate to give shareholders the opportunity to ratify the decision of the Audit Committee. Neither the Audit Committee nor the Board will be bound by the shareholders’ vote, but they may take it into account in future determinations regarding the retention of the Company’s independent registered public accounting firm.

Representatives of KPMG are expected to be present at the Annual Meeting. They will have an opportunity to make a statement, if they so desire, and are expected to be available to respond to appropriate questions from shareholders.

Ratification of the selection of KPMG will require the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on this proposal.

• Vote Recommendation: Your Board recommends you vote “For” the ratification of the independent registered public accounting firm, KPMG LLP, as the independent auditor of the Company for the fiscal year ending December 31, 2018.

Independent Registered Public Accounting Firm Fees:

The following table sets forth the aggregate fees billed to the Company and its subsidiaries for the fiscal years ended December 31, 2017 and 2016, by the Company’s independent registered public accounting firm, KPMG.

Voting Item 3 – Advisory Approval of Say on Pay

Summary and Board Recommendation:

Item 3 is a proposal to approve on an advisory basis the Company’s executive compensation (“Say on Pay”), as described in the Compensation Discussion and Analysis section. This vote is not intended to address a specific item of compensation, but rather the overall compensation of the Named Executive Officers (“NEOs”) and the philosophies, policies and practices as described in this Proxy Statement. Say on Pay is an advisory proposal, so the Company is not required to take any action as a result of this vote. However, the Compensation Committee will be asked to review the results of the shareholder vote to determine if any additional action is required, and it will carefully consider the results as part of its regular review and recommendations regarding executive compensation.

The most recent Say on Pay advisory vote taken at the 2017 Annual Meeting of Shareholders was approved by shareholders.Approval of Say on Pay will require the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on this proposal.

• Vote Recommendation: Your Board recommends you vote “For,” on an advisory basis, the Company’s executive compensation, or Say on Pay.

Say on Pay Details:

The Company believes its executive compensation program is well-designed, appropriately aligns executive pay with Company performance, and attracts, motivates and retains individuals whose interests are aligned with shareholders. Please see the Compensation Discussion and Analysis section for more information on compensation decisions and practices. As noted in the Compensation Discussion and Analysis section, the Company takes a conservative and consistent approach to its executive compensation program. We believe the program ties executive compensation in an appropriate way to corporate and individual performance in order to drive Company growth and shareholder value. We also believe the compensation programs, in total, use responsible and reasonable methods to motivate, retain and reward the NEOs. This approach helps the Company promote long-term profitability within acceptable risk parameters. The Company's key practices are highlighted below:

• Say on Pay: Following the frequency of say on pay advisory shareholder vote at the 2017 Annual Meeting of Shareholders, the Board determined its current intention to include an advisory vote, consistent with the 2017 frequency of say on pay advisory shareholder vote, on executive compensation every year in its proxy statement. This will provide annual feedback from shareholders on the Company's pay practices.

• Employment Agreements: In 2018, consistent with shareholder advisory guidance, the Company's executive employment agreements were revised to provide for change of control "double trigger" severance benefits upon a termination of employment without cause or by the executive for good reason by applying the applicable multiple of two to three times to the sum of base pay plus target bonus for the relevant year instead of applying the multiple to the executive average annual taxable compensation for the five-year period prior to the change of control.

• Conservative: Total executive compensation is conservative as compared to industry standards and the Company's peer group.

• Balanced: The Company's annual bonus plan is a balanced program based on quantitative and qualitative assessment of both the Company’s and the individual executive’s performance. In past years when targeted financial performance was not fully achieved, individually or companywide, based on either objective or subjective standards, or both, bonuses were materially reduced or not awarded at all, in some cases even if threshold levels of performance were in fact achieved.

• Annual Review: The annual bonus is based on goals that are reviewed and updated yearly and are set to encourage long-term profitability within accepted conservative risk parameters.

• Shareholder Aligned: Long-term equity-based incentives, such as stock option awards and restricted stock units ("RSUs"), recognize and encourage an alignment of executives' goals over the long term with those of the shareholders. Awards provide for vesting over a three- to four-year period, which may be incremental or cliff vesting. Stock option awards, even at the highest executive level, are generally modest, and there have been years in which they were not awarded. Exercise prices are determined based on the closing price of the Company’s stock on the day of grant. Stock options only have value if the Company’s stock price increases.

10

• No Backdating or Reloading: The 2013 LTIP under which Company stock options are granted does not permit “backdating” or “reloading” of option grants. Downward repricing of our outstanding stock options is not permitted without shareholder approval.

• Ownership Requirements: NEOs are required to own specific amounts of our stock based on their annual salaries.

• No Tax Gross-Up: The Company does not have tax gross-up plans for NEOs.

• No Golden Parachutes: The Company does not have "golden parachutes" for NEOs; the top change-in-control payment is capped consistent with limits in the Internal Revenue Code so as to prevent the triggering of excess parachute taxes on the Company.

Audit Committee Report

Each member of the Audit Committee qualifies as independent under both the NASDAQ^®standards for independent directors and the more rigorous Securities and Exchange Commission (“SEC”) standards for independent Audit Committee members. For more detail, see the Corporate Governance section. The Audit Committee assists the Board in fulfilling its oversight role relating to the Company’s financial statements and the financial reporting process, including the system of disclosure controls and the Company’s internal controls and procedures. Its duties include reviewing the independent registered public accounting firm’s qualifications and independence, the performance of the independent registered public accounting firm, and the Company’s internal audit function. The duties of the Audit Committee are set forth in the Audit Committee Charter, which has been adopted by the Board and is reviewed annually by the Committee. A copy of the current charter of the Audit Committee is available at www.arrowfinancial.com/corporate/governance.

Management has the responsibility for preparing the Company’s consolidated financial statements and for assessing the effectiveness of its internal controls over financial reporting. The Company’s independent registered public accounting firm, KPMG, has the responsibility for auditing these consolidated financial statements. KPMG reports directly to the Audit Committee, and they meet on a regular basis. The Audit Committee has reviewed and discussed with Management and KPMG the Company’s audited consolidated financial statements as of and for the year ended December 31, 2017. The Audit Committee has also discussed with Management its assertion on the design and effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, and has discussed with KPMG the matters required to be discussed by professional standards. Based on this review and discussion, the Audit Committee recommended to the Board that the audited consolidated financial statements of the Company and its subsidiaries, and Management’s assertion on the design and effectiveness of internal control over financial reporting of the Company and its subsidiaries, be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC.

The Audit Committee has approved the engagement of KPMG as the Company’s independent registered public accounting firm for 2018 and the scope of its work. The Audit Committee has also discussed with KPMG the firm’s assessment of the Company’s internal controls and the matters required to be discussed by Public Company Accounting Oversight Board Auditing Standards No. 1301, “Communications with Audit Committees.” The Audit Committee has received and discussed the written disclosures and the letter from KPMG required by Public Company Accounting Oversight Board Rule 3526, “Communication with Audit Committees Concerning Independence.” The Audit Committee has discussed with KPMG the firm’s independence and determined that the non-audit services provided to the Company by KPMG are compatible with its independence.

Corporate Governance

The Board’s Corporate Governance Guidelines provide the framework within which the Company’s Directors and Executive Officers manage the business and affairs of the Company. The Company is managed under the direction and oversight of the Board. The Board appoints the CEO, who is responsible for the day-to-day operation of the Company. The Board’s primary responsibilities, thereafter, are to oversee management and to exercise its business judgment to act in what it reasonably believes to be the best interests of the Company and its shareholders.

At least once each year, the Board will review the Company’s long-term strategic plans and future key issues. The Board may elect a Lead Director from the independent Directors of the Company to serve as a liaison between the Board Chair and the independent or non-Management Directors and to have such other duties and responsibilities as shall be determined by the Board, including chairing the Executive Sessions of the independent Directors.

The Governance Committee of the Board is responsible for reviewing with the full Board, on an annual basis, the requisite skills and characteristics of all Board members, as well as nominees for Director and the composition of the Board as a whole. This assessment will include whether individual Directors or nominees qualify as independent under applicable law and guidelines, as well as consideration of diversity, age, skills and experience of the Directors as a group in the context of the needs of the Board. A majority of Directors must meet the criteria for general Board independence as required and defined by NASDAQ^®. Directors generally must satisfy certain other applicable laws, rules and regulations.

The Board’s membership is divided into three classes, approximately equal in number. Following the Annual Meeting, the number of Directors in each class will be equal. One class is elected each year by the Company’s shareholders to a term of three years. The Governance Committee identifies and recommends to the full Board suitable candidates for nomination for Director, including, when appropriate, incumbent Directors. In making its recommendations, the Governance Committee will consider any proposals it properly receives from shareholders for Director nominees. Shareholders may propose a Director candidate for consideration by the Governance Committee by following the rules described below under the heading “Shareholder Submissions of Director Nominees for the 2019 Annual Meeting” in the Additional Shareholder Information section. The Governance Committee’s recommendations of candidates for nomination will be based on its determination as to the suitability of the particular individuals, and the slate as a whole, to serve as Directors of the Company, taking into account the criteria discussed above. When evaluating incumbent Directors who are nominated for reelection, the Governance Committee considers, in addition to past performance, each such Director’s attendance record for meetings of the Company’s Board, its subsidiary banks’ boards and committees on which the Director serves, as applicable. See “Director Nomination Process” in the Voting Item 1 – Election of Directors section for a discussion of additional criteria considered in the selection of Directors for nomination.

The Board does not believe that Directors should be subject to term limits. While term limits may in some cases enhance the flow of fresh ideas and viewpoints in the boardroom, they may also result in the loss of knowledgeable and experienced Directors, whose insights into the Company and its operations typically expand and deepen over time. When evaluating whether incumbent Directors should be renominated, the Governance Committee will consider, in addition to the incumbent’s prior performance on the Board, the same general qualities and attributes, such as suitability, character, general experience and background that it applies to new candidates for Director. Additionally, the Company’s Bylaws provide that Directors will retire from the Board at the first Annual Meeting of Shareholders held on or after they attain the age of 75.

Board Leadership Structure:

Currently, the Board leadership structure separates the roles of Chairman and CEO. Mr. Hoy, the Company's retired CEO, serves as Chairman due to his longstanding experience with the Company, along with his strong leadership capability and banking expertise. Mr. Murphy, the Company's President and CEO, is the only member of the Board who is also an employee of the Company. The Board continues to believe this structure is in the best interest of the Company.

12

The Company has a Board comprised largely of Directors who qualify as “independent” under the NASDAQ^®general independence guidelines. Under the Corporate Governance Guidelines, independent Directors, acting as a group, periodically appoint one of their own to serve as Lead Director. The Lead Director chairs the Board’s Executive Sessions, discussed further in “Board Committees” later in this section. The Lead Director also serves as a liaison between the Chair and the independent Directors.Mr. Owens began serving as Lead Director at the 2017 Annual Meeting, succeeding Mr. Carusone upon his retirement. We believe that oversight by the Lead Director, combined with the Company’s overall corporate governance structure, policies and practices as outlined earlier, maximizes the effectiveness of Board leadership. The Governance Committee and the independent Directors will continue to evaluate the Board’s leadership structure as part of its regular review of corporate governance and succession planning to ensure that it remains best suited for the Company and shareholders.

Board Committees:

The Board has three standing committees whose membership and responsibilities must meet certain NASDAQ^®and SEC requirements. These standing committees are the Audit, Compensation and Governance Committees (collectively, the “Committees”). The Board may from time to time establish or maintain additional committees, as it deems necessary or appropriate, the membership of which may include one or more Directors, as well as non-Directors. One such additional committee that the Board has established is the Executive Committee, which is described later in this section.

tCommittee Membership

The Governance Committee regularly reviews committee membership and makes recommendations for changes on an annual basis, with consideration given to the qualifications and preferences of individual Directors and the specific requirements, if any, of NASDAQ^®and the SEC for service on such Committees. The Board gives consideration to rotating committee members periodically, to the extent feasible under applicable laws and regulations governing the membership requirements of the Committees, but the Board does not believe rotation should be mandated as policy, nor that service by a Director on a committee should be subject to term limits. All members of the three standing Committees are independent Directors, as defined (and generally required) under applicable law, rules and regulations (see “Director Independence” later in this section for more detail). A table showing the current members of each of the standing Committees follows:

Director	Audit Committee	Compensation Committee	Governance Committee
Mark L. Behan		X
Tenée R. Casaccio			X
Michael B. Clarke	Chair	X
Gary C. Dake		X	Chair
David G. Kruczlnicki	X	Chair
Elizabeth A. Miller	X		X
David L. Moynehan			X
William L. Owens		X	X
Colin L. Read	X		X
Richard J. Reisman	X

Each of the three standing Committees has its own charter that sets forth the purposes, goals and responsibilities of the committee, as well as the qualifications for membership, procedures for appointing members, structure and operations, and policies for Board oversight of the committee. Each has the power to hire, at the Company’s expense, independent accounting, compensation, financial, legal or other consultants, as the members may deem necessary and appropriate, consistent with the overall authority to retain such advisors as set forth in the committee’s charter, including budgeting or professional conditions and limitations. Management approval will not be required for engagement of consultants, although Management normally will be advised and consulted prior to any such engagement to avoid, among other things, conflicts of interest.

13

tCommittee Descriptions

A description of each of the three standing Committees, as well as the Executive Committee, follows:

• Audit Committee: Mr. Clarke is Chair of the Audit Committee; he has served in this role since 2008. The Audit Committee’s primary duties and responsibilities are to select and appoint the independent auditors each year; monitor the independence and performance of the Company’s independent auditors and internal Audit Department; monitor the quality and integrity of the Company’s financial reporting process and systems of internal controls regarding accounting, financial and legal compliance; and provide a means of communication among the independent auditors, Management, the internal Audit Department and the Board. The Audit Committee also reviews business or financial transactions between the Company and Company insiders and their related parties, such as any transactions with an individual Director or business entity in which the Director has a controlling or material interest. In accordance with applicable rules, the Audit Committee must specifically approve in advance all services performed by the independent auditor. The Audit Committee met four times in 2017, and all then-serving members attended each of these committee meetings.For additional information, see the Audit Committee Report section.

• Compensation Committee: Mr. Kruczlnicki is Chair of the Compensation Committee; he has served in this role since 2013. The Compensation Committee’s principal responsibility is to review and approve, not less often than annually, all aspects of the compensation arrangements and benefit plans covering the Company's Executive Officers, including the CEO, subject to full Board approval, where appropriate. The Compensation Committee also periodically reviews the compensation of the Board and makes recommendations to the full Board with respect to the types and amounts of compensation payable to the Directors for service on the Company’s Board, the boards of its subsidiary banks, and committees thereof. The Compensation Committee also consults with Management and provides general oversight of the compensation and benefit programs and policies for employees. The Compensation Committee met four times in 2017, and with one exception, all then serving members attended each of these meetings. (One member did not attend one of the meetings.) For additional detail regarding executive compensation and the role of the Compensation Committee, see the Compensation Discussion and Analysis section.

• Governance Committee: Mr. Dake began serving as Chair of the Governance Committee following the retirement of Mr. Carusone at the 2017 Annual Meeting. The Governance Committee is specifically charged with establishing procedures with respect to the Director nomination process; reviewing and considering Director nominees, including incumbent nominees, and making recommendations to the Board regarding nominees; reviewing and recommending practices and policies concerning corporate governance; reviewing annually and reporting to the Board regarding the independence of Company Directors and satisfaction by the Board and committee members of applicable requirements or qualifications; reviewing annually and reporting to the Board regarding the performance of the Board; reviewing periodically and making recommendations regarding Company codes of conduct and ethics policies for Directors, Executive Officers and employees and with respect to the Company's committee charters; and reviewing Director training initiatives. The Governance Committee met three times in 2017, and all then-serving members attended each of these meetings.

• Executive Committee: The main purpose of the Executive Committee is to act on matters that may require immediate attention at a time when it is impractical or inconvenient to convene the entire Board. The Executive Committee has the full authority of the Board, subject to certain restrictions established by law or the Company’s governing documents. For example, the committee is not authorized pursuant to the Bylaws to make submissions to shareholders requiring shareholder approval, fill vacancies on the Board or any of its committees, fix compensation of the Board, make changes to the Bylaws, or repeal any prior resolution of the Board. Because the Board believes proper governance involves the entire Board in the Company’s decision process, the Board strives to keep meetings of the Executive Committee to a minimum. The Executive Committee is currently comprised of the Board Chair, Chairs of the three Board Committees, and the Chair of the GFNB/SNB Joint Wealth Management Committee, who is also a Director of the Company. In 2017, the Executive Committee did not hold any meetings since all matters were able to be addressed during meetings of the full Board and/or its standing committees.

14

tExecutive Session

In addition to regular Board and committee meetings, Directors meeting the general independence test under NASDAQ^®meet on occasion in Executive Session to discuss any matters deemed relevant to the Company’s operation and condition. No current or former members of Management are in attendance during these sessions, which are chaired by the Lead Director. Generally, the Lead Director will poll independent Directors prior to or in connection with each Company Board meeting and, if there is a consensus to do so, an Executive Session will be held. Due to the informality and expectation of confidentiality that characterize Executive Sessions, typically no binding corporate decisions or actions are taken nor official records maintained for them. The independent Directors determined that no Executive Sessions were needed in 2017.

tAttendance

In 2017, the Board had four regularly scheduled meetings, one special Board meeting and 11 separate committee meetings. There was 100% attendance at all Board meetings, and all then-current Board members met the requirements of Item 402(b) of the SEC’s Regulation S-K by attending more than 75% of the meetings to which they were invited. Thirteen of the 14 then-current Directors attended the 2017 Annual Meeting of Shareholders.

tCode of Ethics

The Governance Committee has adopted a Business Code of Ethics which applies to all Directors, officers and employees of both the Company and its subsidiary banks. The Business Code of Ethics addresses a wide range of issues and is intended to satisfy the requirements for a code of conduct set forth in the listing standards issued by NASDAQ^®. Additionally, the Governance Committee has adopted a Financial Code of Ethics which applies to the Company’s CEO, CFO, principal accounting officer, controller and any other officers who perform similar functions. The Financial Code of Ethics complies with the SEC’s requirements for a code of conduct established under Section 406 of the Sarbanes-Oxley Act of 2002 and the rules promulgated by the SEC thereunder.

Complete copies of each of the current charters of the Audit Committee, the Compensation Committee and the Governance Committee, as well as copies of the Corporate Governance Guidelines, the Business Code of Ethics and the Financial Code of Ethics are available at www.arrowfinancial.com on the “Corporate Governance” page. The Company intends to post on that page any substantive amendment to, or waiver granted from, the Financial Code of Ethics within four business days of such amendment or waiver.

Director Independence:

Under applicable law and regulation, it is the responsibility of the Board to review and make a determination regarding the independence and qualifications of each member, as well as additional review and determination for members of certain committees.

Under the NASDAQ^®listing standards, a majority of the members of the full Board must meet a general independence requirement. The Board has determined that the following 10 Directors currently meet this requirement: Behan, Casaccio, Clarke, Dake, Kruczlnicki, Miller, Moynehan, Owens, Read and Reisman. The Board has determined that Mr. Hoy is not independent due to his prior service as an Executive Officer of the Company and his continuing service as a consultant since his retirement. See “Director Compensation” within the Voting Item 1 – Election of Directors section for further description of Mr. Hoy’s consulting agreement. Mr. O’Conor retired as an Executive Officer of the Company at year-end 2012 and served for the ensuing four years under a consulting agreement with the Company. As a result, the Board has determined that Mr. O’Conor also is not independent. Mr. Murphy is not independent due to his position as the Company President and CEO.

In making its independence determinations for individual Directors, the Board considers transactions and relationships between (i) the Company and its subsidiaries, and (ii) the Director and/or his or her immediate family or any businesses he or she controls. The Board considers the objective tests for Director independence set forth in the NASDAQ^®listing standards and other regulatory guidelines for such transactions and relationships, as well as a variety of subjective factors, including particular or unique relationships between the Company and the Director, even if such relationships do not exceed the specific dollar threshold that would disqualify them under applicable regulatory guidelines. In its review of Director independence at year-end 2017, the Board considered the following 2017 transactions between the Company and the following individual Directors:

15

• Mr. Behan is the founder and President of Behan Communications, Inc., a public affairs and strategic communications firm with offices in Albany and Glens Falls. During 2017, the Company’s subsidiary bank GFNB made $5,435 in payments to the firm for marketing and public relations consulting services. The Board has determined these minimal payments were well below the objective limits for general Director independence set forth in the NASDAQ^® listing standards and that the Company’s relationship with Behan Communications and Mr. Behan did not compromise his independence.

• Ms. Casaccio is President and part-owner of JMZ Architects and Planners, PC ("JMZ"), an architectural firm located in Glens Falls, New York. In 2016, GFNB engaged JMZ to provide architectural, design and space utilization services for the four buildings located in downtown Glens Falls that represent GFNB’s main campus. The project continued in 2017. Payments to JMZ totaled $67,468 for the year. The Board has determined these minimal payments were well below the objective limits for general Director independence set forth in the NASDAQ^®listing standards and that the Company’s relationship with JMZ and Ms. Casaccio did not compromise her independence.

• Mr. Dake is President of Stewart’s Shops Corporation ("Stewart's"), a large, private company that owns and operates a regional chain of convenience stores. During 2017, Arrow Financial Corporation's subsidiary banks made approximately $221,000 in payments to Stewart’s for rent and incidentals for leased space at market rates and other immaterial purchases. This amount is less than 0.015% of Stewart’s annual gross revenue, which exceeds $1.5 billion. The Board has determined that the Company’s payments were below the objective limits for general Director independence set forth in the NASDAQ^®listing standards and that the Company’s relationship with Stewart’s and Mr. Dake did not compromise his independence. See “Related Party Transactions” later in this section for further information on these business transactions.

• Mr. Owens is Managing Partner at the law firm of Stafford, Owens, Piller, Murnane, Kelleher & Trombley, PLLC (“Stafford Owens”). During 2017, the Company’s subsidiary bank GFNB made $1,927 in payments to Stafford Owens for legal services rendered by the firm to or on behalf of GFNB. Additionally, Stafford Owens received approximately $10,000 in total payments from certain GFNB loan customers in connection with its representation of GFNB at loan closings. The Board determined that the total payments received by Stafford Owens from all sources in connection with the firm's representation of GFNB in 2017 were well below the objective limits for general Director independence set forth in the NASDAQ^® listing standards and the relationship did not compromise Mr. Owen's independence.

• Mr. Read was elected Mayor of the City of Plattsburgh ("City") effective January 1, 2017. GFNB purchased three municipal bonds from the City in 2009 and four in 2017 as part of its regular portfolio transactions. As of December 31, 2017, there was $4,725,000 in outstanding principal under these bonds, which was equal to the maximum principal outstanding balance during 2017. Considering that GFNB was operating consistent with its historical practice in managing its investment portfolio and that the bonds were issued on market terms and are not in default, the Board has determined these bond holdings by GFNB did not compromise Mr. Read’s independence under the rules set forth in the NASDAQ^® listing standards.

There were no “Compensation Committee interlocks,” as defined under the SEC rules, in existence during fiscal year 2017. No member of the Compensation Committee is a current or former employee of the Company or any of its subsidiaries. No member of the Compensation Committee is party to any related party transactions with the Company requiring disclosure by us hereunder except Director Dake (see “Related Party Transactions” later in this section).

In addition to meeting NASDAQ^® general independence standards applicable to Directors, the Directors who serve on the Audit and/or Compensation Committees must meet certain additional independence or regulatory requirements, some of which may be more rigorous than the general standards. The Board has determined that Directors Clarke, Kruczlnicki, Miller, Read and Reisman, who constitute the Audit Committee, all meet the SEC’s more stringent independence requirements for Audit Committee members. The Board has also determined that Directors Clarke, Kruczlnicki and Read each qualify as an “Audit Committee Financial Expert,” as defined by the SEC rules (not all Audit Committee members need to be financial experts). Further, the Board has determined that Directors Behan, Clarke, Dake, Kruczlnicki and Owens, who constitute the Compensation Committee, all meet the independence requirements of NASDAQ^®and the SEC for Compensation Committee members.

Related Party Transactions:

Under the Company’s Statement of Policy with respect to Related Party Transactions, the Audit Committee or the Board itself must approve certain transactions or relationships between the Company and its “related parties,” including Directors and Executive Officers, as well as their immediate family members and controlled companies, if such transactions or relationships in any year will involve an aggregate dollar amount of goods, services or payments in excess of $120,000. Loans from the Company's subsidiary banks to Directors and Executive Officers, their families and controlled businesses, and other related parties, are generally exempt from the above described preapproval policy, as most such loans are subject to Board preapproval under a separate federal banking law, Regulation O.

t2017 Transactions with Related Parties

During 2017, several Directors and Executive Officers and/or their related parties had outstanding loans from one or both of the Company's subsidiary banks in amounts of $120,000 or more. All such loans were made in the ordinary course of business of the bank, on the bank’s standard terms and conditions, and did not involve more than normal risk of collectability or present any other preferential features. As of December 31, 2017, none of these loans were classified by the Company as a non-accrual, past due, restructured or potential problem loan.

A summary of the transactions in 2017 between the Company and a related party that involved an aggregate dollar amount in excess of $120,000 follows.

Under multi-year lease agreements between the Company’s subsidiary banks and Stewart’s, a private company that owns and operates a regional chain of convenience stores, the banks operate five bank offices (three GFNB and two SNB) in premises owned by Stewart’s in which Stewart’s convenience stores are also located. Director Dake is the President of Stewart’s. The Company paid rent and incidental expenses to Stewart’s under these leases in the total amount of approximately $221,000 during 2017. This amount is less than 0.015% of Stewart's annual gross revenue, which exceeds $1.5 billion. One GFNB lease has an original duration of 20 years, expiring in 2019, with a renewal option for two additional 10-year terms. A second GFNB lease has an original duration of 10 years, expiring in 2020, with a renewal option for three additional five-year terms. The third GFNB lease has an original duration of 10 years, expiring in 2023, with a renewal option for three additional five-year terms. One of the SNB leases has a duration of three years, expiring in 2019, with a renewal option for two additional three-year terms. The other SNB lease has a duration of three years, expiring in 2018, with a renewal option for one additional three-year term. These five bank offices are in high-traffic locations. In connection with its approval of the leases, the Board determined that the terms of the leases were, in its opinion, no less favorable from the Company’s perspective than could be obtained by it from a non-related party for comparable premises in an arms-length transaction.

Mr. Read was elected Mayor of the City of Plattsburgh effective January 1, 2017. GFNB purchased three municipal bonds from the City in 2009 and four in 2017 as part of its regular portfolio transactions. As of December 31, 2017, there was $4,725,000 in outstanding principal, which was equal to the maximum principal outstanding during 2017. During 2017, under these bonds and consistent with the bond terms, the City did not pay any principal amounts but did pay aggregate interest to GFNB of $47,062.50. Interest rates for the bonds are 2.25%, 2.375%, two at 3%, 4%, and two at 4.25%.

Board Risk Oversight:

The Board has responsibility for the oversight of risk management within the Company. The Board and its Committees regularly discuss and review with Management the areas of material risk exposure, the potential impact of such risks on the Company, the steps taken to monitor Company exposure to these risks and the controls adopted to mitigate such risk exposure. The Committees assist the Board in fulfilling its oversight responsibilities throughout the year, as follows:

• Audit Committee: Reviews financial risk exposures by monitoring the independence and performance of the Company’s internal and external auditors, and the quality and integrity of the Company’s financial reporting process and systems of internal controls.

• Compensation Committee: Reviews all aspects of the compensation paid to Executive Officers, Directors and employees in general. The committee assesses the ways, if any, in which any aspect of its executive compensation program may, as an unintended consequence, incentivize action or activities that expose the Company to inappropriate risks.

17

• Governance Committee: Focuses on the management of risks associated with Board organization, membership and structure, through its nomination process and Director independence assessment, its review of the organizational and governance structure of the Company, and its periodic review of Board practices and policies concerning corporate governance and the Board’s performance.

In addition to these Board Committees, the Company has an Enterprise Risk Management (“ERM”) Committee at the Management level to assist the Board by providing reasonable assurance regarding the achievement of the Company’s strategic objectives and to enhance the long-term value of the Company. The ERM Committee uses a Board-approved program that is applied both strategically and tactically, and is designed to identify, and manage on a holistic basis, potential and actual risks that may affect the Company. It is based on principles in the "Enterprise Risk Management – Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and other regulatory guidance. The Board receives periodic reports from the ERM Committee, which is chaired by the Chief Risk Officer and includes senior and other designated managers as appropriate. The Chief Risk Officer’s primary function is to oversee risk management as well as regulatory and compliance requirements. The Chief Risk Officer reports directly to the Company President and CEO.

Shareholder Communications with the Board of Directors:

Any shareholder communication that is sent generally to the Company or the Board is directed to the Corporate Secretary, who will review it and advise the Board of the communication. Any such shareholder communication that is directed to an individual Director, Directors or a committee of the Board will be forwarded by the Corporate Secretary to such Director(s) or committee. The Corporate Secretary will retain and make available all such communications for review by the appropriate parties and will periodically summarize and report all such shareholder communications to the Board. Shareholders may communicate to the Board, to an individual Director or Directors, or to a particular committee of the Board by sending or directing such communication either by email to corporatesecretary@arrowbank.com or in writing to: Board of Directors – Shareholder Communications, c/o Corporate Secretary, Arrow Financial Corporation, 250 Glen Street, Glens Falls, New York 12801. If the shareholder intends such communication to be delivered to an individual Director, specific Directors, or particular committee of the Board, we request that this information be prominently displayed at the beginning of the communication.

5% Shareholders:

The following table sets forth the beneficial ownership of the Company’s common stock as of February 26, 2018, the record date for the 2018 Annual Meeting, by the one holder known by us to be the beneficial owner of more than 5% of the outstanding shares of the Company's common stock on such date. Beneficial ownership includes all shares of common stock for which the person or entity has sole or shared voting power or investment power.

Name	Shares Owned		Percent
BlackRock, Inc. 55 East 52nd Street New York, NY 10055	976,063	(a)	7.00	%	(b)

(a) The listed number of shares of the Company’s common stock by BlackRock, Inc. ("BlackRock") is based solely upon a Schedule 13G, Amendment No. 8, filed by BlackRock on January 29, 2018 with the SEC. In that schedule, BlackRock reported that as of December 31, 2017, it had sole dispositive power over all of these shares and the sole voting power with respect to 950,576 shares. BlackRock is an asset management company that provides asset management services to numerous mutual funds.

(b) Percentage based on 13,934,036 shares of the Company's common stock outstanding on February 26, 2018.

The Company's subsidiary banks, GFNB and SNB, in their capacities as fiduciary of numerous accounts in their respective Wealth Management departments, including, in the case of GFNB, as trustee of the Company's Employee Stock Ownership Plan (“ESOP”), held between them 1,726,746 shares of the Company's common stock, or 12.4% of the total shares outstanding and entitled to vote on the record date. However, GFNB and SNB were the beneficial owners of only a relatively small number of these shares. Other persons, such as the individual ESOP participants, had the sole power to vote and/or direct the disposition of most of these shares. As a result, neither GFNB nor SNB were the beneficial owners of more than 5% of the shares of the Company's common stock outstanding and entitled to vote on the record date.

Compensation Discussion and Analysis

Overview:

The Compensation Discussion and Analysis section of our Proxy Statement provides our shareholders with an explanation of our Named Executive Officer compensation philosophies, programs, policies and decisions. Determining executive compensation involves consideration of a number of factors - including business environment, company performance and key events and milestones that take place throughout the year. The Company also has a system in place to align our compensation plans with our shareholders’ best interests.

t2017 Business Environment and Performance

The Company’s subsidiary banks, GFNB and SNB, operate and compete in a mature banking market that is characterized by intense and growing competition and high consumer expectations. We also own two insurance agencies located in and serving the same geographic area as many of our current bank offices.

The Company’s conservative business model emphasizes a strong capital position, high loan quality, knowledge of our market and responsiveness to our customers. Results for the fiscal year ended December 31, 2017, include:

Shareholder Return	Growth	Asset Quality
A 3% stock dividend was distributed to shareholders during 2017. Cash dividends paid effectively increased 3%. Stockholders’ equity reached a record high of $249.6 million at year-end, up 7.2%. Tangible book value per share increased 7.9% to $16.18.	Total assets increased to a record high of $2.760 billion. The loan portfolio increased 11.3% to a record high of $1.951 billion. Total deposit balances grew 6.1% to $2.245 billion.	Nonperforming assets were only 0.28% of total assets as of December 31, 2017. Net loan losses represented just 0.06% of average loans outstanding for the year.

Please refer to our 2017 Annual Report on Form 10-K for five- and 15-year comparisons of the total cumulative return (assuming reinvestment of dividends) for our common stock, as compared to the Russell 2000 Index, the NASDAQ^®Banks Index and the Zacks $1B-$5B Bank Assets Index.

tKey Compensation Decisions and Actions

The business environment and our performance impacted various compensation decisions. The following is a summary of key decisions and actions regarding executive compensation in 2017 and thus far in 2018.

• Short-Term Incentive Plan Awards: In January of 2017 and 2018, bonus awards for NEOs were made in accordance with the Short-Term Incentive Plan (“STIP”) based on the achievement in the prior calendar year of specified performance results of the Company and the individual NEOs, respectively. Actual bonus payouts as a percentage of target were 113% on average in 2017 for our NEOs.

• Long-Term Incentive Plan Awards: In January of 2017 and 2018, grants of stock options were made to the NEOs under the 2013 Long Term Incentive Plan. These awards were made, in each case, in light of individual and corporate accomplishments in the prior year and to incentivize accomplishments for the upcoming years. The goal of the 2013 LTIP is to align our NEOs' interests with those of our shareholders and to foster a long-term performance orientation among our management team.

• Comprehensive Review and Evaluation of CEO Compensation: In 2017, the Compensation Committee engaged its independent compensation consultant to perform a comprehensive analysis of our Chief Executive Officer’s total annual compensation. The independent consultant evaluated the competitiveness and structure of the current arrangement and proposed a select number of changes to

21

align the CEO's compensation more strategically with the Company’s compensation objectives, as well as prevailing market practice among similarly situated financial institutions. The three key changes from the review that were approved in early 2018 were (1) the incorporation of an annual Restricted Stock Unit grant that vests after three years and is settled ratably over 10 years post-retirement (2) the enhancement of the CEO’s existing Select Executive Retirement Plan and (3) the increase in STIP bonus target incentive award from 40% to 50% of base salary for 2018.

• New Employment Agreements: In January 2018, the Company entered into new employment agreements with each of Messrs. Murphy, Campanella, DeMarco, and Kaiser that were modified from previous versions to contain a new change of control severance definition. The previous employment agreements provided for change of control severance based on a multiple of W-2 earnings whereas the new agreements utilize a more customary metric based upon base salary and target bonus. Also, the agreements were revised to provide that no termination payments would be made unless the executive signs and delivers a separation and release agreement in a form acceptable to the Company.

• CFO Change: Edward J. Campanella was appointed Senior Vice President, Treasurer and CFO effective September 5, 2017. He received a competitive compensation arrangement that is consistent with other Named Executive Officers at our Company. Our former Executive Vice President, Treasurer and CFO, Terry R. Goodemote, retired.

tExecutive Compensation Program Highlights

The Board of Directors, Compensation Committee and Management are committed to an effective compensation program that attracts and retains key executive talent, appropriately rewards performance and aligns the interests of our executives and our shareholders, focusing upon our shareholders to enhance value for all of our stakeholders, including shareholders, customers, employees and the communities we serve. Some features of the program are summarized below:

• Hedging and Pledging Policies: The Company has hedging and pledging policies for its Executive Officers who are subject to the SEC’s Section 16 reporting requirements. The policy prohibits Section 16 Officers from entering into financial transactions designed to hedge or offset any decrease in market value of Company common stock. (These policies also apply to Directors.) In addition, the Company requires Board approval prior to the pledging of any Company stock by an NEO.

• Clawback Policy: The Company may seek to recover any incentives paid or payable to an NEO on the achievement of financial or operational goals that subsequently are deemed by the Company to be inaccurate, misstated or misleading.

• Stock Ownership Policy: The Company has a stock ownership policy for NEOs. They are required to own a number of shares of the Company’s common stock equal in value to three times base salary for the CEO and equal in value to one times base salary for other NEOs. Until the required ownership is attained, this policy restricts the NEO’s ability to sell shares of the Company’s common stock obtained through the 2013 LTIP (or predecessor plans).

• No Tax Gross-Ups: The Company does not pay any taxes that are owed by its NEOs.

• Double-Trigger Mechanism: Employment agreements for all NEOs include a “double-trigger” mechanism for change-of-control payments. In addition to a change-of-control event, the NEO must also be terminated without cause or terminate his own employment for good reason in order to receive severance payments under the agreement. If terminated for cause, the NEO would not receive any cash severance payment or enhanced retirement benefits beyond the benefits described in “Potential Payments Upon Termination or Change of Control” within the Agreements with Named Executive Officers section.

• No Stock Option Repricing: The Company has never repriced stock options. The 2013 LTIP prohibits repricing without shareholder approval.

• Independent Consultants: The Compensation Committee has periodically engaged an independent compensation consultant to perform a comprehensive review of our executive compensation program and provide advice on a variety of compensation issues.

22

• Risk Assessment: The Company implements a robust risk oversight and assessment framework to monitor our compensation programs for excessive risk to the Company or its shareholders.

2017 Compensation Philosophy and Program:

The purpose of our executive compensation program is to attract and retain key executives and to motivate our executives to improve the Company’s long-term profitability within acceptable risk parameters. Annual determinations regarding executive compensation are based on corporate and individual performance, taking into account compensation paid to executives at comparably sized banks in our geographic area or similar areas.

Our executive compensation program consists of base salary, annual incentives, long-term incentives, ownership guidelines and executive benefits. The following is a discussion of the primary purpose of each element:

tBase Salary

Base salaries are set to recognize the responsibilities associated with the position and expectations with respect to the individual’s contribution to the Company. In setting or adjusting base salary levels for our NEOs, the Company considers the following factors: the executive’s position, individual performance, contribution to the Company, market salaries for similar positions, experience in that position, industry merit budgets, the Company’s overall financial performance, and the individual’s role in that performance. Base salaries for the NEOs are reviewed and approved annually by the Compensation Committee, usually in January so the Compensation Committee can take into account performance results from the complete prior fiscal year. Other factors considered by the Compensation Committee include leadership and professional standing in the field of banking and financial services, commitment to the community and current market pay position relative to market benchmarking. Under the employment agreements into which the Company enters with individual NEOs, the Company’s ability to decrease the base annual salary of the NEO during the term of the agreement is limited. See the Agreements with Named Executive Officers section later in this Proxy Statement.

tAnnual Incentives

All short-term incentive bonus awards under our STIP are designed to reward Company and individual performance relative to our annual performance goals. Our STIP is based on a comprehensive quantitative and qualitative assessment of both Company and individual performance. In setting goals under the STIP, the Compensation Committee considers multiple inputs, including but not limited to: specific financial goals, relative performance to our industry and individual performance. If circumstances arise such as major corporate transactions, unforeseen significant changes in the economy or industry-wide developments of an unexpected nature, the Compensation Committee may review and revise pre-established performance targets. The Compensation Committee, in its sole discretion, will determine, on a case-by-case basis, whether an NEO will receive a bonus award for the year and, if so, the amount of this bonus. No NEO has a contractual right to a bonus award under the STIP.

Each year, the Compensation Committee sets goals that will result in bonus awards only in years of successful financial performance by the Company. The target bonus award for an NEO is expressed as a percentage of that NEO’s base salary. For 2017, the bonus target awards for our NEOs were 40% of base salary for Mr. Murphy and 30% of base salary for Messrs. DeMarco, Goodemote and Kaiser. Mr. Campanella, who became our CFO in September 2017, had a bonus target award for 2017 of 30% of base salary, pro-rated based on the term of his employment. For 2018, the bonus target awards are 50% of base salary for Mr. Murphy and 30% of base salary for Messrs. Campanella, DeMarco and Kaiser.

The pool for the annual short-term incentive bonus awards to all eligible officers and employees of the Company is generally determined based on the total target awards for all participants for that year. Individual STIP awards may be adjusted above or below the target amount for the participant by the Compensation Committee based not only on the individual’s performance but also on Company performance, with the following limitations: (i) there will be no bonus awards to NEOs if the Company’s performance is less than 90% of target performance, and (ii) if the Company’s performance is greater than 110% of the target performance, the bonus awards are capped at 150% of the target payment.

Determining the amount of the annual short-term incentive bonus awards for an NEO consists of the following three-part process:

23

1. Company Performance: First, the Company’s performance is assessed on a weighted combination of five financial performance measures, which the Compensation Committee believes provide an appropriate portfolio of performance goals and a balanced perspective while ensuring sound risk management. The following table shows the performance measure and goal-weighting for 2017:

Company Performance Measure	Weighting for Goals (CEO)	Weighting for Goals (Other NEOs)
Net Operating Earnings using Internal NOE	60%	80%
ROE using Internal NOE	10%	5%
Efficiency Ratio	10%	5%
Non-Performing Loans	10%	5%
Net Charge-Offs	10%	5%

In measuring net income for the purpose of paying short-term incentive bonus awards, the Compensation Committee uses Internal Net Operating Earnings (“Internal NOE”), which is different from U.S. Generally Accepted Accounting Principles (“GAAP”) in that it represents the net income of the Company before taking into account significant nonrecurring items, net of tax. The significant nonrecurring items are reviewed by the Compensation Committee on a case-by-case basis to determine if each item would have a significant impact on the Company’s performance and, therefore, have an impact on the annual short-term incentive bonus awards made to our NEOs under the STIP. The Compensation Committee endeavors to align bonus awards with performance. Items are included to the extent that they are relevant, regularly recurring and deemed to be in the normal course of business operations.

2. Individual Performance: Second, the Compensation Committee performs an overall assessment of the NEO’s performance based on subjective and objective criteria weighted toward Company and team-oriented goals. The Compensation Committee relies on input from the CEO for assessment of the other NEOs.

3. Relative Weighting of Corporate and Individual Performance: The third and final step in assessing an NEO’s ultimate performance for purposes of the short-term incentive bonus awards is the determination by the Compensation Committee of the relative weighting to be assigned to Company performance versus individual performance for that particular NEO. Typically, the relative weighting for NEOs is based on their particular position with the Company. For 2017, Mr. Murphy was evaluated exclusively, or 100%, on the Company’s performance, and Messrs. Campanella, DeMarco, Goodemote, and Kaiser were evaluated 50% on the Company’s performance and 50% on individual performance.

Historically, the Compensation Committee meets at the beginning of each year to determine short-term incentive bonus awards for the previous year, when the Company’s final year-end performance is known and can be accurately measured. At the same meeting, the Compensation Committee also typically sets the STIP goals for the current year.

Although there is a formula for determining the dollar amount of the annual short-term incentive bonus awards under the STIP, the Compensation Committee retains full discretion for making these awards to all our NEOs. Simply meeting pre-established performance thresholds does not require payment of any award. There have been years in which awards could have been paid based on the formula, but were not, because the Compensation Committee did not deem awards to be appropriate based on a more holistic evaluation of both relative and absolute performance.

tLong-Term Incentives

The long-term incentive plan is designed to align the goals of our NEOs with those of our shareholders. Long-term incentive compensation is provided through the Company’s 2013 LTIP, which authorized the issuance of a maximum 450,000 shares of Company common stock, of which340,178 shares remained available at year-end 2017.

24

The 2013 LTIP allows for grants of various types of equity awards, such as restricted stock, restricted stock units and stock options. Historically, the Company has provided long-term incentive compensation only in the form of stock options, which only provide value to our NEOs or any eligible recipients if the Company’s stock price increases. In 2018, we expanded the use of equity incentives to include RSUs for Mr. Murphy. The RSUs granted in 2018 vest 100% after three years, but are not settled until Mr. Murphy has retired. In the event of Mr. Murphy's death or disability, all unvested shares issuable under the RSU would vest and all vested shares would be distributed. If during the term of the RSU, there is a change of control of the Company and, within 12 months after such change of control, (a) the Company terminates the employment of Mr. Murphy, other than for cause (as defined), or (b) Mr. Murphy terminates his own employment with the Company for good reason (as defined), all unvested shares issuable under the RSU would vest and all vested shares would be distributed. In the event Mr. Murphy is terminated for cause (as defined), all unvested RSUs would be forfeited. The long-term incentive component of our executive compensation program is intended to recognize and reward effective management performance that creates shareholder value, which encourages alignment of our NEOs' interests with those of our shareholders. Equity awards are discretionary and, when awarded by the Compensation Committee, typically reflectto some degreethe Company’s and the individual’s prior-year performance. Stock options granted under our long-term incentive plan normally vest 25% per year over a four-year period, which reinforces the long-term nature of the grant and promotes retention of our top performers. The exercise price for stock option awards is set at 100% of the market closing price of the stock on the date of grant. The Company’s annual stock option awards are generally granted in January each year, shortly after the close of the Company’s fiscal year. Furthermore, the provisions of our long-term incentive plan do not allow “backdating” or “reloading” of option grants.

tStock Ownership Policy

In order to align the interests of the NEOs with those of our shareholders, NEOs are required to own a number of shares of the Company’s common stock equal in value to three times base salary for the CEO and equal in value to one times base salary for other NEOs. Until the required ownership is attained, this policy restricts the NEO’s ability to sell shares of the Company’s common stock obtained through the 2013 LTIP (or predecessor plans). These stock ownership requirements are measured by the Compensation Committee each year, using holdings valued as of December 31 of the previous year. Common shares owned outright or vested shares held through benefit plans are currently counted toward the stock ownership requirement. Conversely, unexercised stock options and unvested awards do not count toward the stock ownership requirement. Individuals have five years from appointment or promotion as an NEO to meet these requirements. The independent members of the Board have the discretion to address and approve exceptions on a case-by-case basis.

tExecutive Benefits

The executive benefit program is intended to provide appropriate security and benefits for our NEOs, allowing them to focus on managing the business. Generally, NEOs are eligible for the benefits package we offer to our full-time employees, which includes medical, dental, life/long-term disability insurance and qualified retirement plans. In addition, our executive compensation program includes other select benefits summarized below. These benefits are provided in furtherance of the goal of providing NEOs with a comprehensive and competitive compensation package, taking into consideration both market and best practices. All forms of executive benefits are reviewed and approved by the Compensation Committee.

• Broad-based and Select Executive Retirement Plans: The Company provides a qualified retirement plan (with a non-matching 401(k) feature) as well as an ESOP to all eligible full-time employees, including NEOs. The Company may provide additional retirement benefits to NEOs on a case-by-case basis, either through the Company’s non-qualified Supplemental Executive Retirement Plan ("SERP") or through individual awards to NEOs of additional retirement benefits under some other tax-qualified or nonqualified plan or program. There are two types of awards under the SERP, each of which may be granted at the Compensation Committee’s discretion: (i) a “makeup” benefit that is designed to provide the recipients with a level of benefit that they would have received under the Retirement Plan if there were no limitations on eligible compensation in the Internal Revenue Code, and (ii) an additional award of special retirement benefits to any NEO or other senior executive prior to his or her retirement to reward special service and contribution to the Company. As of December 31, 2017, Messrs. Murphy, DeMarco and Kaiser were all designated to participate in the makeup benefit feature under the first part of the SERP. In 2018, the Compensation Committee approved the adjustment of Mr. Murphy’s existing arrangement to increase the formula for pay-based credits up to 30% of eligible compensation. Further, the Compensation Committee approved an award of special retirement benefits to Mr. Murphy, providing him with an annuity payable at a

25

normal retirement age of 65 that is equal to 40% of his compensation, averaged over 60 consecutive calendar months which produce the highest average during the last 120 consecutive calendar months of Mr. Murphy’s employment, offset by his Social Security retirement benefits that would be payable at age 65 and further offset by the actuarial value of other qualified and non-qualified plan benefits derived from contributions made by the Company.

• Deferred Compensation Plan: The Company maintains a nonqualified deferred compensation plan for NEOs under which they may elect to defer some or all of their salary and bonus until retirement. The deferred amounts accumulate interest at a rate equal to the highest rate currently being paid on individual retirement accounts by GFNB. Although all of the NEOs were eligible to participate, none did in 2017. This deferral plan is further discussed in “Nonqualified Deferred Compensation” within the Executive Compensation section.

• Executive Perquisites: The Company provides very limited perquisites to its NEOs. Messrs. Murphy, DeMarco, Goodemote and Kaiser in 2017 each received the personal use of a company automobile and reimbursement of country club dues or a golf course membership. No other perquisites were provided. As part of his separation agreement, Mr. Goodemote received a 2011 vehicle.

• Employment Agreements with Named Executive Officers: Historically, the Company has entered into employment agreements or limited change-of-control agreements with its NEOs. The Company currently has a three-year employment agreement with Mr. Murphy and two-year agreements with Messrs. Campanella, DeMarco, and Kaiser. In January of each year, the Compensation Committee reviews the key terms of each NEO employment agreement and determines whether to offer the NEO a replacement agreement of at least the same duration and otherwise at least as favorable to the NEO as his current agreement.

The Company entered into new employment agreements with Messrs. Murphy, Campanella, DeMarco, and Kaiser effective February 1, 2018. The four replacement employment agreements contain standard terms relating to salary, position, duties and benefits, as well as severance payments following a change of control of the Company accompanied or followed by a termination of the NEO’s employment by the Company other than for cause or by the NEO himself for good reason. These agreements provide for participation in certain plans, but do not provide any right to receive a payment under the STIP, to receive stock awards under the LTIP, or to receive any additional retirement benefits under our retirement plan or SERP. The Compensation Committee and our Board will continue to review the appropriateness of employment agreements on a case-by-case basis. The employment agreements are described in more detail in the Agreements with Named Executive Officers section.

The Company from time to time enters into consulting agreements with retiring Executive Officers to ensure a smooth transition of an operating function from the retiree to his or her successor and/or to ensure the Company has access to the retiree's expertise for a period of time. Mr. Hoy, the Company’s former CEO, serves under such a post-retirement consulting arrangement through December 31, 2018; this agreement is further described in “Mr. Hoy's Consulting Agreement” within the Voting Item 1 – Election of Directors section.

The Company believes these five components – base salary, annual incentives, long-term incentives, ownership requirements and executive benefits – comprise a total compensation program that retains and appropriately rewards key executive talent, aligns the financial interests of our NEOs with the interests of our shareholders, and supports a total rewards approach to executive compensation. Our executive compensation program is reviewed at least annually by the Compensation Committee to ensure that various considerations such as security versus performance, fixed versus variable, short-term versus long-term, cash versus equity-based compensation, and benefits provided are and remain appropriate in light of market trends and the Company’s primary business objectives. Our policy and practice is to consider the Company’s performance compared to peer and industry performance, as well as market compensation levels, when making our short- and long-term compensation decisions to ensure our compensation package effectively reflects performance.

2017 Process for Determining Executive Compensation:

tRole of the Compensation Committee, Independent Consultants and Management

The Compensation Committee oversees our executive compensation policies and process, is responsible for the final decisions on components of executive compensation for the CEO and the other NEOs, and makes recommendations to the full Board as needed. The Compensation Committee is responsible for reviewing and approving all aspects of compensation of our CEO and other NEOs, and it receives input from the CEO and the full Board on key compensation policy issues.

The Compensation Committee is authorized to seek the assistance of independent compensation consultants. These consultants are paid by the Company, but are hired by, directed by and report directly to the Compensation Committee. During 2017, the Compensation Committee retained the services of Pearl Meyer & Partners, LLC (“Pearl Meyer”), an independent outside consulting firm specializing in executive and board compensation, to provide assistance regarding executive compensation and support with compensation policies and proxy disclosure. Pearl Meyer provided no other consulting services for the Company in 2017.

Our CEO provides the Compensation Committee with an annual review of his own goals for the Company, including broad performance and individual goals, as well as a performance assessment for each of the other NEOs. Management also provides information and data on Company and individual performance and executive compensation to the Compensation Committee. Although our CEO provides insight and recommendations regarding NEO compensation, the Compensation Committee votes on decisions regarding NEO compensation. Where appropriate, the Board will also make recommendations or determinations or give its approval regarding NEO compensation. Although the Compensation Committee meets with our CEO to obtain his views, goals and assessments regarding compensation matters, as discussed above, the decisions regarding his compensation package are made solely by the Compensation Committee without the CEO or other NEOs present.

tBenchmarking

In setting program targets and making compensation decisions, the Compensation Committee uses a variety of data sources and information related to market practices for bank holding companies similar to ours. The Compensation Committee may engage independent compensation consultants on a periodic basis to conduct comprehensive competitive reviews.

The Compensation Committee considers a select number of key reports, summarized below, to provide market-competitive information for base salary, short- and long-term incentive targets, and estimated total direct compensation, with ranges for performance. This information allows the Compensation Committee to see potential pay and range of pay for executive roles, and it provides context for the Committee in setting targeted pay levels going forward.

Each year, the Compensation Committee reviews peer group data – from the Executive Compensation Review for Banks and Thrifts prepared annually by SNL Financial (“SNL”) – to obtain executive compensation and performance data relative to a peer group. Further, the Compensation Committee reviews annually a survey compiled by Management of the executive compensation paid by regional and local financial institutions based on their most recent proxy statements.

In addition, the Compensation Committee periodically commissions an independent outside consulting firm to conduct a comprehensive review of the Company’s executive compensation program. In 2015, Pearl Meyer conducted an independent and objective analysis of all elements of compensation, individually and in aggregate, relative to market and peer group practices (“Pearl Meyer Report”). Pay mix and an assessment of the pay-for-performance relationship were also presented to the Compensation Committee.

A primary data source used in the Pearl Meyer Report for determining the competitive market for NEO compensation was the information publicly disclosed by a peer group of other publicly traded banks. This peer group was developed by Pearl Meyer using objective parameters that reflect bank holding companies of similar asset size located in our general geographic region.

The Pearl Meyer Report 2015 peer group, which is listed below, consisted of 18 bank holding companies in Connecticut, Maine, Massachusetts, New Jersey, Ohio, Pennsylvania, Virginia and Vermont that ranged from approximately $1 billion to $3 billion in assets, positioning the Company at approximately the median for size:

27

Blue Hills Bancorp, Inc.        First Connecticut Bancorp, Inc.        Peapack-Gladstone Financial Corp.    

Camden National Corp.        First Defiance Financial Corp.        Peoples Bancorp Inc.

Citizens & Northern Corp.        Hampton Roads Bankshares, Inc.    Peoples Financial Services Corp.

CNB Financial Corp.        Merchants Bancshares, Inc.        Sun Bancorp, Inc.

Enterprise Bancorp, Inc.        OceanFirst Financial Corp.        Univest Corporation of Pennsylvania

First Community Bancshares, Inc.    Orrstown Financial Services, Inc.     Westfield Financial, Inc.

In addition to the regional peer group data, the Pearl Meyer Report used data from other banking industry surveys that reviewed bank holding companies of similar asset size and regions to that of the Company.

In 2017, Pearl Meyer conducted an independent and objective analysis of all elements of compensation for the CEO position, relative to market and peer group practices (the “Pearl Meyer CEO Report”). Like the 2015 Pearl Meyer Report, the primary data source used in the Pearl Meyer CEO Report for determining the competitive market for CEO compensation was the information publicly disclosed by a peer group of other publicly traded banks. This peer group was developed by Pearl Meyer using objective parameters that reflect banks of similar asset size located in our general geographic region.

The 2017 peer group contained in the Pearl Meyer CEO Report, which is listed below, consisted of 20 companies in the mid-Atlantic and Northeast that ranged from approximately one-half to two times the asset size of Arrow Financial Corporation, positioning the Company at approximately the median for size:

Bar Harbor Bankshares    First Bancorp, Inc.            Peoples Bancorp, Inc.

Blue Hills Bancorp, Inc.    First Community Bancshares, Inc.    Peoples Financial Services Corp.

Bryn Mawr Bank Corp.    First Connecticut Bancorp, Inc.         Sun Bancorp, Inc.

Camden National Corp.    First Defiance Financial Corp.         Univest Corporation of Pennsylvania

CNB Financial Corp.     HarborOne Bancorp, Inc.        Washington Trust Bancorp, Inc.

Enterprise Bancorp, Inc.    OceanFirst Financial Corp.        Western New England Bancorp, Inc.

Financial Institutions, Inc.    Peapack-Gladstone Financial Corp.    

tPerformance Analysis

In addition to benchmarking, the Compensation Committee and Board also review the Company’s performance relative to other bank holding companies in a broader peer group as defined in the Federal Reserve Bank’s “Bank Holding Company Performance Report,” which contains data from a peer group consisting of all U.S. bank holding companies with between $1.0 billion and $3.0 billion in total assets (“Fed Peer Group”).

Set forth below is a comparison between the Company’s financial performance across several key performance metrics for the 12-month period ended December 31, 2017, and the performance across these same metrics for the nine-month period ended September 30, 2017, by the Fed Peer Group – the most recent information available at the time the Compensation Committee met in January to review performance.

This comparison shows that the Company continued to be among the top-performers and that our operating results and asset quality ratios withstood the ongoing stresses of the financial sector better than many of our competitors in this national peer group.

Key Performance Metric	Arrow Financial Corporation 12/31/2017		Federal Reserve Bank Peer Data 09/30/2017
Profitability Ratios (Higher is Better)
ROA – Return on Average Assets	1.09	%	0.99	%
ROE – Return on Average Equity	12.14	%	9.19	%
Asset Quality (Lower is Better)
Net Loans Charged-Off as a Percentage of Average Loans	0.06	%	0.08	%
Nonperforming Loans as a Percentage of Period-End Loans	0.31	%	0.73	%
Efficiency Ratio (Lower is Better)	56.96	%	65.29	%

Executive Compensation Decisions:

tJanuary 2017 Base Salary Decisions

The Compensation Committee met in January 2017 to review corporate and individual executive performance for 2016. Please see our 2016 Annual Report on Form 10-K for a detailed review of the Company’s 2016 financial performance.

Based on the performance of the Company and the individuals, the Compensation Committee approved the base salaries below for the Named Executive Officers effective January 1, 2017.

Named Executive Officer	2016 Salary (as of 7/1/16)		January 2017 Raise		2017 Salary (as of 1/1/17)
			% of Base Salary	Amount
Thomas J. Murphy	$400,000	(a)	10%	$40,000	$440,000	(a)
David S. DeMarco	$250,000		6%	$15,000	$265,000
Terry R. Goodemote	$240,000		—	—	$240,000
David D. Kaiser	$210,000		7.1%	$15,000	$225,000

a) Mr. Murphy’s 2016 salary was $332,000 on January 1, 2016; it was subsequently increased to $400,000 on July 1, 2016. His January 2017 increase was part of a strategy to bring his pay in line with competitive market levels as well as his performance and contributions as CEO. The Committee will continue to monitor changes in this area going forward.

In connection with Mr. Goodemote's retirement, Mr. Campanella was hired in September 2017 as our CFO. His initial base salary was $225,000.

tJanuary 2018 Base Salary Decisions

The Compensation Committee met in January 2018 to review corporate and individual executive performance for 2017. Please see “2017 Business Performance” earlier in this section and our 2017 Annual Report on Form 10-K for a detailed review of the Company’s 2017 financial performance.

Based on the performance of the Company and the individuals, the Compensation Committee approved the base salaries below for the Named Executive Officers effective January 1, 2018.

Named Executive Officer	2017 Salary	January 2018 Raise		2018 Salary
		% of Base Salary	Amount
Thomas J. Murphy	$440,000	11.4%	$50,000	$490,000
Edward J. Campanella	$225,000	4.4%	$10,000	$235,000
David S. DeMarco	$265,000	9.4%	$25,000	$290,000
David D. Kaiser	$225,000	4.4%	$10,000	$235,000

t Short-Term Incentive Award Decisions

In determining the short-term incentive bonus awards for NEOs at any year-end, the Compensation Committee carefully considers the recent financial performance of the Company, strategic results such as product and market expansion, as well as individual performance factors such as leadership and commitment to the community. The amounts of such awards are principally determined based on the achievement of pre-established Company performance targets, as well as an overall individual assessment. See “Annual Incentives” earlier in this section for further detail.

At a meeting in January 2018, the Compensation Committee reviewed the parameters and results of the 2017 short-term incentive bonus award goals for its NEOs. Based on the final results of the Company’s performance, the amounts of the short-term incentive bonus awards to be paid under the STIP for Messrs. Murphy, Campanella, DeMarco and Kaiser were determined.

29

As noted under “2017 Compensation Philosophy and Program” earlier in this section, the Compensation Committee uses an NOE calculation to measure its performance goals. Our NOE is different from GAAP in that it eliminates significant nonrecurring items as adjusted for the tax impact. Specifically for 2017, our GAAP income of $29.326 million was reduced by the $1.116 million positive result of the Tax Cuts and Jobs Act of 2017 and increased by the $448 thousand net loss recognized by the Company on the sale of investment securities that were held available for sale. Net of income taxes, the Internal NOE was approximately $841 thousand lower than the GAAP net income for 2017. The Compensation Committee determined that the exclusion of these items and the consideration of additional factors were appropriate for purposes of determining the annual STIP bonus awards. It should be noted that, for 2017, the Internal NOE of $28.484 million was $984 thousand above the $27.500 million goal, so an adjustment was made to the 2017 STIP calculation for this significant positive difference.

The following table provides a comparison of the Company’s 2017 target performance goals, the 2017 actual results and 2017 peer data (through September 30, 2017) drawn from the Federal Reserve Bank’s Bank Holding Company Performance Report. The weighting used by the Compensation Committee in determining annual awards is described earlier in this section. The Federal Reserve Bank Peer Group Data provided in this table consisted of all U.S. Bank Holding Companies having between $1.0 billion and $3.0 billion in total assets. The peer group data was the most recent available during the Compensation Committee’s review at the January 2018 meeting.

Performance Measure	2017 Goal	2017 Actual	Federal Reserve Bank Peer Data 09/30/17
Net Operating Earnings “Internal NOE”	$27.5 million	$28.484 million	N/A
ROE using Internal NOE (Higher is Better)	≥ 12%	11.80%	9.19%
Efficiency Ratio (Lower is Better)	≤ 57%	56.96%	65.29%
Non-Performing Loans (Lower is Better)	≤ 0.50%	0.31%	0.73%
Net Charge-Offs (Lower is Better)	≤ 0.15%	0.06%	0.08%

The Company’s financial performance for 2017 was above many of the established target levels and exceeded peer group performance across these metrics, based on the performance of the Fed Peer Group. The amount of the STIP award for each individual NEO was based upon these corporate considerations, as well as individual performance toward the established 2017 goals. The Compensation Committee approved the following 2017 STIP awards at its January 2018 meeting:

Named Executive Officer	2017 Annual Incentive Target Awards		2017 Annual Incentive Actual Awards
	Amount	% of Base Salary	Amount	% of Base Salary
Thomas J. Murphy	$176,000	40%	$207,000	47.05%
Edward J. Campanella (a)	$22,500	10%	$26,500	11.78%
David S. DeMarco	$79,500	30%	$93,500	35.28%
Terry R. Goodemote	$72,000	30%	$40,000	16.67%
David D. Kaiser	$67,500	30%	$80,000	35.56%

a) Mr. Campanella's STIP award was pro-rated based on the term of his 2017 employment. His percentage of Base Salary Annual Incentive Target was 30%, which, when pro-rated for his service to the Company in 2017, was reduced to 10%.

30

tJanuary 2017 Long-Term Incentive Award Decisions

At its January 2017 meeting, the Compensation Committee decided to make stock option awards consistent with the grants of January 2016. The following stock option awards were granted at an exercise price of $37.20, the closing price of our common stock on the date of grant and vest ratably over a four-year period:

Named Executive Officer	Stock Option Grants in January 2017 (# shares)	Grant Date Fair Value of January 2017 Option Awards
Thomas J. Murphy	10,000	$64,400
David S. DeMarco	5,000	$32,200
Terry R. Goodemote	5,000	$32,200
David D. Kaiser	5,000	$32,200

tJanuary 2018 Long-Term Incentive Award Decisions

At its January 2018 meeting, the Compensation Committee decided to make stock option awards consistent with the grants of January 2017. The following stock option awards were granted at an exercise price of $32.80, the closing price of our common stock on the date of grant, and vest ratably over a four-year period:

Named Executive Officer	Stock Option Grants in January 2018 (# shares)	Grant Date Fair Value of January 2018 Option Awards
Thomas J. Murphy	10,000	$57,585
Edward J. Campanella	2,000	$11,517
David S. DeMarco	5,000	$28,793
David D. Kaiser	5,000	$28,793

In addition to the annual stock option grants awarded to the NEOs, Mr. Murphy received 3,279 RSUs that vest 100% after 3 years of service and are settled over a 10-year period beginning one year after his retirement. The RSU grant value represents 25% of Mr. Murphy’s fiscal year end base salary.

Other Compensation-Related Matters:

tRisk Oversight

The Board of Directors, Compensation Committee, and Management will continue to ensure that proper policies are maintained to monitor compensation levels carefully to ensure they reflect an appropriate balance of pay-for-performance within acceptable risk parameters. We believe incentive compensation awards should be aligned with the institution’s overall business strategy and support its desired risk profile. To that end, each year Management conducts an internal compensation risk assessment to understand the various elements of its overall compensation program, including all incentives. As part of the exercise, in 2017, Management completed an inventory of our existing compensation programs, including incentives; evaluated the plans; determined the existence of Management and Committee oversight; considered appropriate risk mitigants; and assigned a risk rating based on documentation to support these controls. The Company recognizes that an effective incentive program should encourage and reward appropriate performance and requires an appropriate amount of risk-taking, which is in the long-term benefit of the Company and shareholders. Based on our evaluation, the Company has determined its compensation programs and policies do not create excessive and unnecessary risk taking. Our determination is supported by the following key attributes:

31

• Our compensation program contains an appropriate balance of fixed and variable compensation.

• The Company offers incentive compensation in multiple forms, including, historically, the award of stock options that are tied to multi-year performance and vest over time.

• Our STIP contains both a threshold and maximum payment, protecting the Company from the extreme levels of risk that accompany unlimited upside incentive compensation programs and inappropriate pay and performance alignment. Although there is a formula for determining the dollar amount of the annual STIP bonus awards, the Compensation Committee retains full discretion for making STIP bonus awards to our Executive Officers. There have been years in which these awards could have been made based on the formula but were not given to the Executive Officers.

• The Company has share ownership guidelines that further promote and incentivize long-term thinking to serve the best interests of the Company.

• Our benefits programs are competitive with the market and provide for reasonable base line levels of health, welfare and security, further enhancing the risk-mitigating aspects of our overall program.

• We have adopted a “clawback” policy that will allow us to seek to recover any incentive paid or payable to an Executive Officer on the achievement of financial or operational goals that subsequently are deemed by the Company to be inaccurate, misstated or misleading.

The Company and its Board, including the Compensation Committee, will continue to ensure that proper policies are maintained to monitor ongoing risk management and assessment of compensation practices.

tImpact of Accounting and Tax on the Form of Compensation

The Compensation Committee and Management consider the accounting and individual and corporate tax consequences of the compensation plans prior to making changes. The Compensation Committee has considered the impact of the expense, which will be recognized by the Company in accordance with FASB ASC TOPIC 718, on the Company’s use of equity incentives.

Section 162(m) of the Internal Revenue Code limits deductibility by the Company of non-exempt taxable compensation paid to NEOs to a maximum of $1 million per annum. Based on the current salaries being paid to our NEOs and the expected range of possible future performance awards that might be paid to our NEOs in upcoming years, the Company does not believe that the non-deductibility for tax purposes of any component of the compensation payable to its NEOs under Section 162(m) is a likely concern but will continue to evaluate this issue in future years.

Compensation Committee Report:

The Compensation Committee of the Board has reviewed and discussed with Management the Compensation Discussion and Analysis section, as required by Item 402(b) of the SEC’s Regulation S-K and the Compensation Committee’s Charter. Based on its review and discussion, the Compensation Committee has recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

(a) This column sets forth the dollar value of option awards granted under the Company’s compensatory stock plans for each of the listed years, calculated in accordance with FASB ASC TOPIC 718. The estimated value of each stock option granted under the 2013 LTIP, in each case using the Black-Scholes model to estimate fair value, $5.78 per option share in 2015 (all grants were made January 28, 2015); $5.77 per option share in 2016 (all grants were made January 27, 2016) and $6.44 per option share in 2017 (all grants were made January 25, 2017). All such stock options vest ratably in equal installments over the first four anniversaries following the date of grant.

(b) This column sets forth the short-term incentive bonus payments made under the Company’s STIP for each of the listed years, based on the financial performance of the Company, strategic Company results and individual performance factors during that year. STIP amounts payable for a given year are generally paid in January of the succeeding year.

(c) This column sets forth the actuarial increase during each of the listed years in the present value of the retirement benefits under qualified pension plans and nonqualified deferred compensation plans established by the Company that cover such NEO, determined using interest rate, mortality rate and other assumptions consistent with those used in the Company’s financial statements. The increase in present value of retirement benefits reported for each of the NEOs for 2017 includes (i) under the Company’s Employees’ Pension Plan (“Pension Plan”), $42,003 for Mr. Murphy, $60,450 for Mr. DeMarco, $50,508 for Mr. Goodemote and $46,863 for Mr. Kaiser and (ii) under the Company’s SERP, $45,797 for Mr. Murphy, $9,006 for Mr. DeMarco, $4,624 for Mr. Goodemote and $2,302 for Mr. Kaiser.

(d) Mr. Murphy’s annual salary was $332,000 from January to June; it increased to $400,000 in July, resulting in an average of approximately $366,000 for the year.

(e) Mr. Campanella joined the Company on September 5, 2017, at which time his annualized base salary was $225,000.

(f) Although his last day of employment was December 31, 2017, Mr. Goodemote's last day as CFO was September 4, 2017.

(g) All Other Compensation includes the following components for 2017:

Name	Company Contribution to ESOP	Life Insurance Premiums Paid by Company for Benefit of NEO	Dollar Value of Discount in Share Price for Company Common Stock Purchased Under Employees' Stock Purchase Plan	Perquisites Received Greater than $10,000		Total Other Compensation

David D. Kaiser	$15,629	$385	$189	$12,290	(c)	$28,493

(a) Messrs. Murphy, Campanella and DeMarco did not receive more than $10,000 in perquisites in 2017.

(b) Mr. Goodemote received a country club membership, personal use of a Company vehicle and, as part of his separation agreement, a 2011 vehicle with an estimated fair market value of $9,100.

(c) Mr. Kaiser received both a country club membership and personal use of a Company vehicle.

Grants of Plan-Based Awards Table:

As noted in the Compensation Discussion and Analysis, the Company provides officers and key employees with both an annual short-term incentive plan (STIP) and a long-term incentive plan (LTIP) to attract and retain such officers and employees and to motivate them to improve the Company’s short- and long-term performance, respectively.

The STIP bonus payable to covered individuals, including NEOs, is based on a comprehensive quantitative and qualitative assessment of both Company and individual performance. The target incentive awards, if awards are made for the year, are defined as a percentage of the covered person’s base salary. For 2017, the STIP bonus target incentive awards for the NEOs were 40% of base salary for Mr. Murphy and 30% of base salary for Messrs. Campanella (pro-rated based on his date of employment), DeMarco, Goodemote and Kaiser. For 2018, the STIP bonus target incentive awards for the NEOs are 50% of base salary for Mr. Murphy and 30% of base salary for Messrs. Campanella, DeMarco and Kaiser. The amounts listed in the table below represent each NEO’s 2017 target incentive award, as well as his threshold incentive award (50% of target) and maximum incentive award (150% of target). The Compensation Committee, in its sole discretion, will determine on a case-by-case basis whether an NEO will receive a STIP bonus payment for the year and, if so, the amount of this bonus, which typically falls within the limits set forth above. Because a STIP bonus payment is discretionary, no NEO has a contractual right to a bonus under the STIP for any given year, even if the pre-established quantitative performance standards for the Company or the Company function for which the NEO is responsible have been met for such year, or the NEO’s individual performance standards have been met. There have been years in which the Company and the NEOs have satisfied their quantitative or individual performance targets but no STIP bonuses have been declared or paid, as determined by the Compensation Committee.

34

Historically, the Company has limited its grants of stock-based awards under its long-term incentive plans to stock options. However, in January 2018, the Company awarded Mr. Murphy some restricted stock units. (See "January 2018 Long-Term Incentive Award Decisions" in the Compensation Discussion and Analysis section for a description of the material terms of this award.) The Company’s 2013 LTIP (and predecessor plans) authorize the granting of stock options and other stock-based awards as a long-term incentive component within the overall compensation program.

(a) The threshold incentive award to any covered person under the STIP, including an NEO, is not the minimum bonus payment such person may receive under the STIP. The Compensation Committee may choose to pay a bonus under the STIP to any covered person,including an NEO, that is less than their threshold incentive award, or not to pay such person any bonus under the STIP, even if applicable performance thresholds or targets have been met by the Company and/or such person for the year in question.

(b) Mr. Campanella was hired as CFO in September 2017. As a result, his estimated future payouts under the non-equity incentive plan were pro-rated to mirror his four months of service. He did not receive any long-term incentive awards in 2017.

Outstanding Equity Awards at Fiscal Year-End Table:

The following table shows all outstanding stock-based awards held by each NEO as of December 31, 2017. All such awards consist of stock options to acquire the Company’s common stock granted under the Company’s 2013 LTIP (or predecessor plans).The number of shares and exercise prices on this table have been adjusted for the 3% stock dividend distributed on September 28, 2017.

(a) All stock options vest ratably in equal installments over the first four anniversaries following the date of the grant.

(b) Mr. Campanella was hired as CFO in September 2017 and held no outstanding equity awards at December 31, 2017.

(c) In connection with Mr. Goodemote's retirement from the Company and consistent with the underlying award agreements, unvested options held by Mr. Goodemote on December 31, 2017 were forfeited and he has three additional months to exercise vested options held by him on his last day of employment.

Option Exercises and Stock Vested Table:

The following table sets forth information regarding the stock options that were exercised by each NEO during 2017:

Name	Option Awards
	Number Shares Acquired on Exercise (a)	Value Realized on Exercise (b)
Thomas J. Murphy	8,117	$88,758
Edward J. Campanella (c)	—	—
David S. DeMarco	4,141	$63,440
Terry R. Goodemote	—	—
David D. Kaiser	3,138	$58,681

(a) Represents the total number of shares subject to stock options that the NEO exercised during the year.

(b) Represents the “spread” of options on the date of exercise, i.e., the difference between the dollar value of the shares of common stock for which options were exercised, based on the market price of the Company's common stock on the date of exercise, and the exercise price (purchase price) of such shares under the options.

(c) Mr. Campanella was hired as CFO in September 2017 and held no options in 2017.

Pension Benefits Table:

The Company maintains a qualified retirement plan for eligible employees who have attained the age of 18, completed one year of service and work a minimum of 1,000 hours per calendar year. Eligible compensation under the retirement plan includes salary, overtime, sick pay, bonuses and other cash and non-cash benefits.

Participants in the retirement plan with 25 years of service may retire at any age, participants with 10 years of service may retire at or after age 55, and participants with five years of service may retire at or after age 65. For early retirement prior to age 65, annuity payments, if elected, would be reduced by 0.25% for each month the participant elects to retire before age 65. Participants who are eligible to retire may not commence receipt of their benefit prior to age 55.

The Company maintains an unfunded, non-qualified SERP, in part for the benefit of NEOs, as determined by the Compensation Committee on a case-by-case basis. The SERP contains both a qualified retirement plan “makeup” benefit feature and a special additional SERP benefit feature. For those NEOs who qualify and are selected to participate in the “makeup” benefit feature, the award basically provides enhanced installment payments post-retirement that are designed to give the NEO the overall level of retirement payments he would have received under the qualified retirement plan alone if there were no limitations on maximum retirement payments to high-paid personnel in the Internal Revenue Code. Under the additional SERP benefit feature, the Compensation Committee is authorized to grant to selected Executive Officers additional payments upon their retirement, beyond their SERP “make-up” benefit payments. Such additional payments are also typically structured as post-retirement installment payments, the amounts of which are determined on a case-by-case basis by the Compensation Committee at or before the time of retirement. Messrs. Murphy, DeMarco, Goodemote and Kaiser participate in the “make-up” benefit feature of the SERP. In 2017, none of the NEOs participated in the special additional benefit feature of the SERP. In January 2018, Mr. Murphy was provided a special SERP award. See "Broad-based and Select Executive Retirement Plans" in the Compensation Discussion and Analysis section for a description of the material terms of the award.

The following table sets forth the present value of accumulated benefits under both the qualified and non-qualified retirement plans of the Company payable to each NEO as of December 31, 2017, and the number of years of service credited to them under the plans. The present value was determined using interest rate and mortality rate assumptions consistent with those described in Note 13 in Item 8 of the Company’s consolidated financial statements as of and for the fiscal year ended December 31, 2017, as included in the Company’s Annual Report on Form 10-K.

Nonqualified Deferred Compensation:

The Company has an Executive Officer Deferred Compensation Plan (“Officers’ Deferral Plan”) under which an Executive Officer may elect on a year-to-year basis to defer until retirement all or a portion of his salary or bonus payments otherwise payable to him during and for such year. Amounts deferred earn interest at a rate equal to the highest rate currently paid on individual retirement accounts by GFNB. None of the NEOs elected to defer under the plan salary or bonus amounts payable to them in or for 2017 or in or for the prior two years.

Pay Ratio Disclosure:

The Company's compensation program is designed to motivate all employees to carry out the Company Mission: value our customers, empower our employees, care for our communities, and deliver for our shareholders. The Company aims to pay appropriate compensation at all levels within the Company.

The 2017 total annual compensation of the median employee taking into account all Company employees who were employed as of December 31, 2017, other than our President and CEO Mr. Murphy, was $46,370. Mr. Murphy’s 2017 total annual compensation was $815,846. The ratio of these amounts was reasonably estimated to be 1-to-18.

As of December 31, 2017, our total employee population, excluding Mr. Murphy, consisted of 526 employees who are all located in the United States. To identify the median compensated employee, a comparison of the total wages or salary of our employee population as reflected in Box 5 of Form W-2 was completed.

The 1-to-18 pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

38

Agreements with Named Executive Officers

Employment Agreements:

The Company has employment agreements with Messrs. Murphy, Campanella, DeMarco and Kaiser. Mr. Murphy serves as President and CEO of both the Company and GFNB; Mr. Campanella serves as Senior Vice President, Treasurer and CFO of the Company and Executive Vice President, Treasurer and CFO of GFNB; Mr. DeMarco serves as Senior Vice President and Chief Banking Officer of the Company, Executive Vice President and Chief Banking Officer of GFNB and President and CEO of SNB; and Mr. Kaiser serves as Senior Vice President of the Company and Chief Credit Officer of GFNB. Effective February 1, 2018, Messrs. Murphy, Campanella, DeMarco and Kaiser entered into new employment agreements with the Company, replacing their prior employment agreements. Mr. Murphy’s agreement is for a three-year term and the agreements of Messrs. Campanella, DeMarco and Kaiser are each for a two-year term. At the beginning of each calendar year, the Board is required under these agreements to consider and vote upon a proposal to replace each of the agreements with new, comparable agreements having similar terms, conditions and benefits.

Under each agreement, the NEO is guaranteed his current base annual salary and certain other benefits for the duration of the agreement. Also under each agreement, the NEO is entitled to participate in certain other benefit plans, including medical, dental and life insurance plans; is eligible for (although not entitled to receive) cash awards under the short-term annual incentive bonus plan and equity-based awards under the long-term incentive plan; and is also eligible to participate in various retirement and supplemental retirement plans. In the event the NEO is terminated other than for “cause” or terminates his own employment for “good reason,” the NEO will receive a lump-sum payment equal to the greater of (i) the dollar amount of base salary that would have been payable to him during the remaining term of the agreement or (ii) one year’s base salary.

Additionally, under the agreements, if during the term of the agreement there is a change of control of the Company and, within 12 months after such change of control, either (i) the Company terminates the employment of the NEO other than for cause or (ii) such NEO terminates his own employment with the Company for good reason, the NEO will be entitled to receive an aggregate dollar amount, payable in installments over a two-year period following the date of his termination (or in a lump sum, in the event of unforeseeable emergency), equal to two or three times the sum of the executive's (a) annual base salary and (b) target bonus under the short-term incentive plan for the relative year (the "Base Amount"), subject to downward adjustment to reflect the value of any other “change of control” payments or benefits he might receive following such change of control. In the case of Mr. Murphy, the multiple is three times the applicable Base Amount, and in the cases of Messrs. Campanella, DeMarco and Kaiser, the multiple is two times the Base Amount, subject, in each case, to downward adjustment to reflect the value of any other “change-of-control” payment or benefits the NEO might receive under other compensatory arrangements then in effect. In such circumstances, the NEO shall be entitled to receive medical, dental and life insurance coverage that is generally equivalent to the coverage then held by him on the date of his termination, subject to employee cost-sharing, for a period of two years following such date. Under each agreement, the NEO will not receive any payment following a change of control to the extent such payment constitutes an “excess parachute payment” under the Internal Revenue Code.

Each of the employment agreements for Messrs. Murphy, Campanella, DeMarco and Kaiser contain non-compete and non-solicitation provisions. For a period of two years following the termination of the NEO’s employment, for any reason, he is generally precluded from being employed by, an owner of, or adviser to any bank or insured financial institution located in any New York county in which the Company or its subsidiaries provide financial services, maintain a branch or office or have acted to establish a branch or office. Under the non-solicitation provision, for a period of two years following the NEO’s termination of employment for any reason, he is generally precluded from soliciting customers or clients of the Company or its subsidiaries on behalf of any other financial institution that provides financial services. The NEO is also precluded from employing or soliciting employees of the Company or its subsidiaries on behalf of another corporation or entity. The agreements also contain confidentiality and non-disparagement covenants in favor of the Company.

Separation Agreement:

Effective September 5, 2017, Mr. Goodemote no longer served as Executive Vice President, Treasurer and CFO. His employment continued through December 31, 2017 during which time he assisted in an advisory capacity with the

39

transition of his duties to Mr. Campanella. On November 1, 2017, the Company and Mr. Goodemote signed an Executive Separation Agreement and Release (the “Separation Agreement”). Pursuant to the Separation Agreement, the Company agreed to pay Mr. Goodemote separation pay of $260,000 in installments over the 2018 calendar year. He will also be eligible to receive certain additional benefits, including, among other things, (1) continued medical, dental and life insurance contributions; (2) benefits under the Company’s retirement plans as set forth by the terms of the applicable plans; (3) any award to be paid according to the Company’s short-term incentive plan, pro-rated for the term of his service as an officer during 2017, which resulted in an award in the amount of $40,000; and (4) continued rights of indemnification and directors and officers liability insurance with respect to the period of his service as an officer of the Company. Consistent with the underlying award agreements, on December 31, 2017, unvested options held by Mr. Goodemote were forfeited and he has 90 additional days to exercise vested options held by him on his last day of employment. The benefits provided in the Separation Agreement, including the separation payment, are provided by the Company in consideration of and contingent upon compliance with certain releases, representations, warranties, covenants and agreements made by Mr. Goodemote therein, including, but not limited to, covenants of confidentiality and non-solicitation. Pursuant to the Separation Agreement, the Company waived its rights to enforce a non-competition covenant set forth in the Employment Agreement dated February 1, 2016 by and among Mr. Goodemote, the Company, and GFNB.

Potential Payments Upon Termination or Change of Control:

Mr. Goodemote's rights upon his termination of employment were determined in accordance with the Separation Agreement described above. Accordingly, this section is only applicable to NEOs Murphy, Campanella, DeMarco, and Kaiser. The description below is based on a theoretical change of control on December 31, 2017.

tTermination for Cause

In the event of a termination of any NEO for cause, the NEO in question would not receive any cash severance payment or enhanced retirement benefits beyond the benefits described in the “Pension Benefits Table” within the Executive Compensation section. Eligibility for regular Company severance or retirement payments is determined in a manner consistent with all employees of the Company under applicable Company plans and policies.

tTermination by the Company Other Than for Cause

If there is a termination of any of the NEOs by the Company other than for cause, the NEO is entitled under his current employment agreement with the Company to receive a lump-sum payment in an amount equal to the greater of (i) his base salary payable during the remaining term of the agreement or (ii) one year’s base salary. The table later in this section shows the estimated payouts for Messrs. Murphy, Campanella, DeMarco and Kaiser, had they been terminated by the Company other than for cause as of December 31, 2017.

The Company does not have a formal written severance plan or policy that generally covers employees or executives who are terminated by the Company other than for cause; therefore, none of the NEOs would be entitled to any additional severance payments under any such policy or plan if terminated by the Company other than for cause. However, the Company does have a SERP, in which Executive Officers such as NEOs are eligible to participate, if so determined by the Compensation Committee. In 2017, as selected by the Compensation Committee, Messrs. Murphy, DeMarco and Kaiser participated in the “make-up” benefits feature of the SERP. Additionally, Mr. Murphy was recently selected to participate in the additional special benefits feature. See "Broad-based and Select Executive Retirement Plans" in the Compensation Discussion and Analysis section for a description of the material terms of the award.

For further information concerning the SERP, see the discussion accompanying the “Pension Benefits Table” in the Executive Compensation section. In the past, the Company has, from time to time at the discretion of the Board or its Compensation Committee, awarded severance payments to NEOs in differing amounts, determined on a case-by-case basis, even in cases where such payments were not required under the SERP or under the terms of any employment agreement between the Company and such officer. Except as discussed above and with regard to Mr. Murphy's recent award described in "Broad-based and Select Executive Retirement Plans" in the Compensation Discussion and Analysis section, any termination by the Company of an NEO other than for cause would not generally result in enhanced retirement benefits beyond the benefits described in the “Pension Benefits Table” in the Executive Compensation section. (The foregoing discussion assumes that the hypothetical termination of an NEO by the Company other than for cause is not preceded by a change of control. Any such termination following a change of control may result in a greater payment to the NEO, as discussed later in this section.)

40

tTermination for Good Reason

Each of the current NEO employment agreements provides for payments to the NEO if he were to voluntarily terminate his employment for “good reason.” Good reason is defined as a (i) failure by the Company to offer the NEO an annual replacement agreement on terms, conditions and benefits comparable to his existing employment agreement; (ii) material diminution in his title, authority, duties or responsibilities; (iii) required relocation of the NEO more than 100 miles from his existing base location of employment; or (iv) material breach by the Company of the NEO’s employment agreement. Under each NEO’s agreement, the amount due to the NEO if he were to terminate his employment for good reason during the term of the agreement, is a lump-sum payment equal to the greater of the amount of (i) his base salary payable during the remaining term of the agreement or (ii) one year’s base salary. For a discussion of the impact of a voluntary termination by an NEO of his own employment on any retirement benefits due him under the Company’s qualified retirement plan or under the Company’s nonqualified SERP or any payments under any other severance plan or policy, see the discussion in the preceding section, “Termination by the Company Other Than for Cause.” (The foregoing discussion assumes that the hypothetical termination of the NEO by the Company other than for cause is not preceded by a change of control. Any such termination following a change of control may result in a greater payment to the NEO, as discussed later in this section.)

tTermination in Connection with a Change of Control

Under the employment agreements with each of the NEOs, certain payments are to be made by the Company to each NEO if, following a change of control of the Company, his employment is terminated without cause or he voluntarily terminates his employment for good reason. For the NEOs, the amounts that would have been payable to each had his employment been terminated as of December 31, 2017, by the Company or by such officer himself for good reason following a change of control are identified in tables later in this section, other than in respect to Mr. Goodemote whose separation pay is described above. In addition, all of the outstanding stock options granted to these NEOs, to the extent not fully vested, would under the terms of such options vest immediately upon a change of control, regardless of whether the employment of such person is terminated or terminates on or after such change of control. Other than the foregoing, termination of any of the NEOs following a change of control would generally not result in enhanced retirement benefits beyond the benefits described in the “Pension Benefits Table” in the Executive Compensation section. Eligibility for other payments would be determined in a manner consistent with all Company employees under applicable plans and policies.

A “change of control” of the Company is defined in the employment agreements with NEOs as follows: (i) the acquisition by one person, or more than one person acting as a group, of ownership of stock of the Company that, together with stock held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the stock of the Company; (ii) the acquisition by one person, or more than one person acting as a group, of ownership of stock of the Company that, together with stock of the Company acquired during the 12-month period ending on the date of the most recent acquisition by such person or group, constitutes 30% or more of the total voting power of the stock of the Company; (iii) a majority of the members of the Board are replaced during any 12-month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or (iv) one person, or more than one person acting as a group, acquires, or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or group, assets from the Company that have a total gross fair market value, determined without regard to any liabilities associated with such assets, equal to or more than 40% of the total gross fair market value of all of the assets of the Company immediately before such acquisition(s).

tVoluntary Termination or Early Retirement

In 2017, the early retirement or voluntary termination of employment by any NEO (other than a voluntary termination of employment by the NEO for “good reason,” which is discussed separately above) would generally not result in any enhanced retirement benefits beyond the benefits described in “Pension Benefits Table” in the Executive Compensation section. To the extent that any NEO may hold unvested stock options as of the date of his self- termination or early retirement, the Board might choose to accelerate the vesting of such options as of the date of such termination or early retirement. Eligibility for regular Company severance or retirement payments by an NEO is determined in a manner consistent with all Company employees under applicable plans and policies. Participation in either the “makeup” benefit feature or the special additional benefit feature of the SERP, including in the event of early retirement, is limited to select Executive Officers, as determined from time to time by the Compensation Committee acting in its sole discretion. Messrs. Murphy, DeMarco, and Kaiser are currently eligible for SERP payments upon their termination of employment or early retirement.

41

tDeath or Disability

In the event of death or disability, the NEO would generally not receive any cash severance payment or enhanced retirement benefits beyond those described in “Pension Benefits Table” within the Executive Compensation section. Eligibility for regular Company severance or retirement payments is determined in a manner consistent with all employees of the Company under applicable plans and policies. However, under the standard stock option award agreements applicable to all option recipients, including NEOs, upon the death or permanent disability of a recipient who holds unvested stock option awards, any such awards will be subject to accelerated vesting as of such date.

Potential Payments Table:

Except in respect of Mr. Goodemote, whose separation pay is described above, the table below shows the estimated potential payments and benefits to each of the NEOs upon various "termination of employment" scenarios, assuming the NEO’s employment terminated as of December 31, 2017; the value of the Company’s common stock was $33.95, the closing price of the common stock on that day; and in the case of a post change-in-control termination, the triggering change-in-control event occurred in 2017.

(a) Assuming termination of an NEO's employment by the Company without cause or by the NEO for good reason within 12 months following a change of control, Messrs. Murphy, Campanella, DeMarco and Kaiser will each receive an amount payable in installments or, in the event of unforeseeable emergency, in a lump-sum equal to, for Mr. Murphy, 2.99 times the average annual compensation for the most recent five taxable years, and in the case of Messrs. Campanella, DeMarco and Kaiser, two times the average annual compensation for the most recent five taxable years, in each case adjusted downward to reflect any other change-of-control payment or benefits they might receive under other compensatory arrangements then in effect, such as the value they might receive from accelerated vesting of stock options. Their agreements further provide that under no circumstances will Messrs. Murphy, Campanella, DeMarco and Kaiser receive payments under the employment agreements if such payments would constitute an “excess parachute payment” under the tax laws.

(b) Messrs. Murphy, Campanella, DeMarco and Kaiser will each receive a lump-sum payment equal to the greater of the amount of (i) their base salary payable during the remaining term of the agreement in effect on December 31, 2017 or (ii) one year’s base salary.

(c) Reflects accelerated vesting of stock options.

42

(d) Represents $122,546 for benefits under the SERP pension plan and $61,984 for SERP ESOP account value for Mr. Murphy; $24,748 for benefits under the SERP pension plan and $13,372 for SERP ESOP account value for Mr. DeMarco; and $2,302 for benefits under the SERP pension plan for Mr. Kaiser. SERP pension plan benefits are payable in the form of an annuity and SERP ESOP account values are payable in a lump sum.

(e) Represents the projected cost for 24 months of medical and dental insurance coverage under the Company’s fully insured medical and self-insured dental plans, assuming continued cost-sharing by the NEO, plus continued premium payments for 24 months of term life insurance and split-dollar insurance policies.

(f) For Mr. Murphy, the lump-sum amount $1,512,692 is adjusted downward by $161,829 as a result of accelerated vesting of stock options. For Mr. Campanella, the lump-sum amount $450,000 is not adjusted as he had no stock options at year-end. For Mr. DeMarco, the lump-sum amount $598,801 is adjusted downward by $80,935 as a result of accelerated vesting of stock options. For Mr. Kaiser, the lump-sum amount $489,148 is adjusted downward by $59,527 as a result of accelerated vesting of stock options.

Section 16(a) Beneficial Ownership Reporting

The Company’s Executive Officers and Directors, as well as any 10% shareholders of the Company, are required by Section 16(a) of the Securities Exchange Act of 1934 to file reports with the SEC regarding their ownership of Company stock, including changes in their stock ownership. The Company has received and reviewed copies of these reports filed by the Company’s Directors and Executive Officers during 2017, along with written statements received from the Directors and Executive Officers stating they were not required to file any additional reports. Based solely on the Company's review of these 2017 reports and statements, all but one of the Section 16(a) reports required to be filed by the Directors and Executive Officers during 2017 were timely filed. Ms. Miller filed one late report, disclosing one transaction.

Additional Voting Information

Frequently Asked Questions:

tWho is entitled to vote?

The Company has one class of stock outstanding, common stock, $1 par value per share. At the close of business on the record date of February 26, 2018, there were 13,934,036 shares outstanding. The holders of these shares are shareholders of record and will be entitled to vote at the Annual Meeting or any adjournment or postponement thereof. Each of these shareholders will receive notice of the Annual Meeting and instructions on how to vote their shares. Each share outstanding on the record date is entitled to one vote. Shares held in treasury by the Company are not eligible to vote and do not count toward a quorum.

tWhat are “broker non-votes” and how are they voted at the Annual Meeting?

Shares of the Company common stock can be held in (i) certificate form; (ii) by “book entry” at the Company's transfer agent, American Stock Transfer & Trust Company, LLC; or (iii) in “street name” at a broker. When shares owned by you are held in street name, the broker will solicit your vote and provide the Company with the results of the vote for all of the Company shares it holds in your account. On “routine” matters, if you as the owner of the shares do not provide the broker with voting instructions, the broker has the right to vote these shares in its own discretion. However, a broker is not allowed to exercise its discretion on voting shares held in street name on any “non-routine” matter. On such matters, these shares may only be voted by the broker in accordance with express voting instructions received by it from you, the owner of the shares. The votes attached to such shares, that is, shares that may not be voted by a broker except in accordance with the owner’s voting instructions, are referred to as “broker non-votes.”

This year, the only matter that will be considered a routine matter is Item 2, the ratification of the Company’s independent registered public accounting firm. Item 1, the election of Directors, and Item 3, Say on Pay, are non-routine matters; therefore, shares held by a broker in street name cannot be voted on by the broker at his or her discretion for that item. If your shares are held at a broker, the Company urges you to provide voting instructions to your broker so that your vote may be counted.

43

tHow are Dividend Reinvestment Plan and other plan shares voted?

Shares owned by you in the Arrow Financial Corporation Automatic Dividend Reinvestment Plan (“DRIP”) on the record date will be combined with all other shares owned by you directly on that date and presented to you with voting instructions. Shares owned by Company employees, Directors and other participants in the Company’s 2011 Employee Stock Purchase Plan as of the February 26, 2018, record date will be presented to the participants for voting on a separate voting form and will be voted in accordance with their instructions.

Shares owned by Company employees in the ESOP on the record date on a fully vested basis will be voted by the ESOP Trustee on behalf of such employees in accordance with any voting instructions received from the employees. Participants will receive a separate voting form from the ESOP’s plan administrator for this purpose. If a participant does not provide the Trustee with voting instructions for his or her ESOP shares, the Trustee will vote the participant’s shares in accordance with the “mirror voting” provisions of the ESOP. Under the “mirror voting” provisions, all such shares will be voted in a pro rata manner calculated to reflect most accurately the instructions received from those account holders who did provide voting instructions to the Trustee.

tWhat constitutes a quorum at the meeting?

There will be a quorum at the Annual Meeting if one-third of the total number of outstanding shares of the Company's common stock are present, either in person or represented by proxy. Consistent with applicable state law and the Company's Certificate of Incorporation and Bylaws, all shares present in person or represented by proxy at the Annual Meeting, including so-called “broker non-votes,” will be treated as shares present or represented by proxy for purposes of determining the meeting quorum. Shares held in treasury by the Company are not deemed outstanding and thus are ignored for purposes of calculating the quorum.

tHow many votes are required for approval of Item 1?

The first item on the agenda is the election of four Class BDirectors . The affirmative vote of the holders of a plurality of the shares of common stock present in person or represented by proxy at the Annual Meeting and eligible to vote on such matter is required for the election of each Director. A “plurality” means receiving a higher number of votes for such position than any other candidate, up to the maximum number of Directors to be chosen at the Annual Meeting.Because there are only as many nominees (four) as there are Directors to be elected (four) at this year’s meeting, a Director nominee is assured of being elected if he or she receives any “For” votes, regardless of how many negative votes (“Withhold Authority”) are cast for that Director. Broker non-votes are ineligible to vote on Item 1.

The Company’s Majority Voting Policy states that if an election of Directors is uncontested, as is the case this year,and a nominee’s negative votes (“Withhold Authority”) exceed 50% of the total number of shares outstanding and entitled to vote at the Annual Meeting with respect to the election of Directors, that Director must tender his or her resignation to the Company following the meeting. The Governance Committee of the Board is then required to evaluate the tendered resignation and make a recommendation to the full Board on appropriate action, which may or may not include the acceptance of such resignation. In determining the appropriate action to be taken by the Company, the Board will take into account the best interests of the Company and its shareholders.

tWhat is the impact of a vote to “Withhold Authority” on Item 1?

In one respect, a proxy or ballot marked “Withhold Authority” will be the equivalent of an abstention from voting on Item 1. As discussed in the preceding section, because there are only as many nominees as there are Directors to be elected, if each of the nominees receives any votes in favor of their election, each will be elected and a ballot marked “Withhold Authority,” like an abstention from voting, will not affect the outcome of this election. However, a ballot marked “Withhold Authority” (a negative vote), unlike an abstention from voting, may nevertheless have a negative impact under the Majority Voting Policy because a “Withhold Authority” vote, unlike a shareholder’s abstention from voting, will be treated as a negative vote under the Company’s Majority Voting Policy and thus will make it somewhat more likely that the nominee will be required to submit his or her resignation under that policy, even though such person may in fact have been elected. (See the description of the Majority Voting Policy in the preceding paragraph.)

tHow many votes are required for approval of Item 2?

The second item on the agenda is ratification of the independent registered public accounting firm, KPMG LLP. The affirmative vote of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on this proposal is required for ratification. Broker non-votes will be eligible to vote on Item 2. A proxy or ballot marked “Abstain” on Item 2 will not have the same effect as a vote “Against” such item. A proxy or

44

ballot marked “Against” on Item 2 is an actual vote (and counts in the total number of votes on the item) whereas a vote to “Abstain” on Item 2 is not an actual vote (and does not get counted in the total votes on the item). Therefore, a vote “Against” Item 2 makes it more difficult to achieve shareholder approval or ratification than a vote to “Abstain.”

tHow many votes are required for approval of Item 3?

The third item on the agenda is the advisory approval of the executive compensation, Say on Pay. The affirmative vote of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on this proposal is required to approve, by advisory vote, the compensation paid to the NEOs. Abstentions and broker “non-votes” will not be counted in determining the number of votes cast and, therefore, will have no effect on the outcome of this vote. A proxy or ballot marked “Abstain” on Item 3 will not have the same effect as a vote “Against” such item. A proxy or ballot marked “Against” on Item 3 is an actual vote (and counts in the total number of votes on the item) whereas a vote to “Abstain” on Item 3 is not an actual vote (and does not get counted in the total votes on the item). Therefore, a vote “Against” Item 3 makes it more difficult to achieve shareholder advisory approval of Say on Pay than a vote to “Abstain.”

tHow do I vote?

If you are a shareholder of record as of the close of business on February 26, 2018, you will be entitled to vote at the Annual Meeting, or any adjournment or postponement thereof. You can ensure that your shares are voted properly by submitting your proxy by calling 1-800-690-6903, visiting www.proxyvote.com or by completing, signing and dating the proxy card that will be provided to you upon request. Shareholders of record should receive a notice with voting instructions and the ability to request Proxy Materials, except those shareholders who have previously requested printed or electronic copies of the Proxy Materials will receive a printed or electronic copy of the proxy card, as applicable.

If your shares are held by a broker or bank, you must follow the voting instructions on the form you receive from your broker or bank.

tMay I revoke my proxy?

A proxy may be revoked at any time prior to the Annual Meeting by submitting a later vote of your shares either online or by telephone prior to the Annual Meeting or by attending and voting your shares in person at the Annual Meeting. You may also revoke your proxy by delivering a written notice of revocation of proxy prior to the Annual Meeting to: Corporate Secretary, Arrow Financial Corporation, 250 Glen Street, Glens Falls, New York 12801.

tHow are proxies being solicited?

Proxies are being solicited electronically, by telephone and by mail. Proxies may also be solicited without additional compensation by Directors, Officers and other employees personally, by telephone or other means. The Company will bear all costs of proxy solicitation. If the Company utilizes the services of other financial institutions, brokerage houses, custodians, nominees or fiduciaries to solicit proxies, the Company will reimburse them for their out-of-pocket expenses.

Householding of Notices to Shareholders:

In some instances, only one copy of the Notice Regarding the Availability of Proxy Materials concerning this Proxy Statement is being delivered for shareholder accounts that contain the same primary Social Security number, unless the Company has received instructions from one or more of the shareholders to continue to deliver multiple copies. The Company will deliver a copy of the Notice Regarding the Availability of Proxy Materials to any shareholder upon request by email to corporatesecretary@arrowbank.com or in writing to: Householding of Notice, c/o Corporate Secretary, Arrow Financial Corporation, 250 Glen Street, Glens Falls, New York 12801.

Additional Matters for Consideration at the Annual Meeting:

Please note the deadline for submission of proposals by shareholders for consideration at the Annual Meeting has passed. This applies to proposals that shareholders might wish to include in the Company’s Proxy Statement for the Annual Meeting (this Proxy Statement), proposals that shareholders might wish to include in their own Proxy Materials, which they would prepare, file with the SEC and disseminate to shareholders, or proposals that shareholders might wish to submit directly to a shareholder vote, in person, at the Annual Meeting. Therefore, no additional matters may be proposed by any shareholder for submission, or submitted, to a vote of the shareholders generally at the Annual Meeting, other than procedural issues such as adjournment, postponement or continuation. On such procedural issues,

45

all shares represented at the Annual Meeting by proxy may be voted at the discretion of the attorneys-in-fact named in the proxies, to the extent permitted by law.

Proxy Cards Returned Without Specific Voting Instructions:

If you return a proxy card without specific voting instructions for any or all items, your shares will be voted “For” each of the Board’sfourClass Bnomineeson Item 1; “For” ratification of the appointment of KPMG LLP on Item 2; “For” Say on Pay on Item 3;and “For” any other procedural matter properly submitted for shareholder consideration, in such manner as the shareholders’ attorneys-in-fact may determine, in their discretion, to be appropriate and in the best interests of shareholders generally.
